Success rarely happens overnight -- especially in business, where success is almost always the result of years of sustained effort.
It takes time to make the right connections. It takes time to build a great team. It takes time to create long-term, loyal customers.

And then there's this: Research shows a 60 year-old startup founder is 3 times as likely to found a successful startup as a 30-year-old startup founder, and is 1.7 times as likely to found a startup that winds up in the top 0.1 percent of all companies.
Just keep in mind that each test yields indications, not certainties. "Passing" any of the following doesn't guarantee lower mortality risk. Shoot, I was in extremely good cardiovascular shape and still had the dreaded 'widowmaker' heart attack. (Although I could argue that my outcome could have been a lot worse had I not been in great shape, so there is that.)
Plus, research shows that achieving a high score -- or working to improve your scores -- can help you perform better under stress. Can elevate your mood for up to 12 hours. Can increase the production of a protein that supports the function, growth, and survival of brain cells. Exercise can even improve attention, concentration, and learning and memory functions.
