I was shivering as I sent my financials to a commercial landlord for approval — I’d been working on this deal for six months.

I’m partnering with a brilliant founder and chef, who’s sandwich concept blew my mind when I first walked in. Think Ray Kroc visiting McDonalds the first time or Sean Parker seeing Facebook and joining Mark Zuckerberg.

Definitely a “hell yes” opportunity. No holds bar.

I stayed in touch with the genius for four years, he had one restaurant at the time. Now he has three so the market validation box is checked. I believe there could easily be one of these little sandwich shops in every city in the world and couldn’t help but jump on the rocket ship.

Six months of negotiating and we came to a deal and found the perfect location that fit our economic model. Some negotiating with the landlord and we signed a letter of intent for a lease.

To my surprise, after all this work, the landlord is now asking us to provide financials. Though they trust this brand and know I’m putting up the capital as a partner.

As I submitted my financials to our landlord, the what-if scenarios began to pop in. I went to sleep that night wondering what they’d say. Besides, I’m not John Rockeffeler by any means and it’s a ten year lease. Landlords are risk analysts and numbers driven.

And then it dawned on me as I woke up the next morning, I know they’re going to give me a shot even though I’m not ultra wealthy as a ‘capital partner’ in this context as I should be.

Why? Because they’re optimistic — and optimists believe in the power of entrepreneurship — and the human spirit that awakens when you take on personal responsibility.

How would landlords know this?

Because they’re smart and successful, and even while being critical, smart and successful people who have walked the walk are optimistic by nature — they have to be to bring big visions to life.

They know our broker wouldn’t have put us forward in the first place if they didn’t believe in us and the brand.

They know I’m risking my capital and and laying it on the line.

They know my partner (a strong restaurant brand in Washington DC) is risking his name and reputation by working with me.

I’m investing in creativity.

I’m creating jobs.

They know these are great things so I know they’ll be optimistic.

One researcher said “high optimism will predict high effort and success”, while another executive said optimism is defined as expectancy judgements that you can do certain things in the future”.

Staying optimistic is a critical habit to become successful (among other benefits) and here are 5 reasons why (and a simple habit at the end).

1. What You Focus On Is What You Get

“You don’t believe what you see, you see what you believe.” — Science

You get what you see, and what you see is based on how you perceive the world.

Is it a ‘cold and ruthless place’? Or is it an abundant place of opportunity?

It’s the things you focus on that determine your mindset, and your mindset determines your results.

One several hundred millionaire took it to the point of not allowing any negativity enter his mind. When he sees news of bad things come on, he leaves the room. When he hears people talking about negative things, he opts out of the conversation.

This is counter intuitive because we often do the exact opposite, using bad things to prop our egos as often as possible.

I’ve recently implemented this strategy, nipping all negative thoughts in the bud. I’m finding they’re coming less and less.

A hack for this is being in great physical/mental shape because when you feel good and have high energy, you are optimistic and can handle anything.

Command your subconscious mind each day and don’t allow negativity to enter it.

2. Not Being Optimistic Is A Waste Of Time

There is silver lining in everything that happens to you. Every. Single. Thing.

Smart and successful people know this and embrace the obstacles and transcend them. In fact, they look forward to them.

If my financials don’t get approved, there’s a reason, that I’m not ready and it’s likely a blessing in disguise. They’re smart folks so I’ll go back to the drawing board until I am ready and I will have gained some very knowledgeable experience as I move forward.

Don’t expect outcomes but embrace whatever outcome that happens.

3. Not Being Optimistic Is More Likely To Drain Energy

Energy is everything, the most important part of execution. The best plan, strategy or anything else is a waste if you don’t have the energy to execute. The articles don’t get written and the calls don’t get made.

Being optimistic saves energy while being pessimistic drains it.

4. Optimism Significantly Affects Physical Health

According to a study conducted by Harvard medical school, having an optimistic attitude early in life can predict better health and a lower rate of death in later stages of life.

A US study gave almost 7,000 students a comprehensive personally test as they entered university and tracked them for the next 40 years. It concluded the most pessimistic individuals had a 42% higher rate of death than the most optimistic.

In Conclusion: Implement optimism with an all or nothing commitment.

If you’re down or pessimistic all the time, it will require zero tolerance to create the new habit.

Do what I learned from the hundred millionaire, don’t let negative thoughts happen to you.

Set a new standard for yourself and soon you’ll always be in a high state with positive attitude (even while you’re being critical).

It’s not about the content, it’s about how it’s said and received.

The people who are reviewing my lease are as smart and successful as they come. A ‘seal team’ of executives managing several million square feet of real estate. Entrepreneurs to the core and numbers driven while intuitive. I know they’ll approach my application with optimism even while being critical — looking for reasons to make it happen and not for reasons to not.

Either way, I know it’s the right call, will embrace the news with optimism and will let you know how it goes.
