Because if we don't evolve we might as well be dead

"Seriously, if you always put limits on what you can do, physical or anything else; it'll spread over into the rest of your life. It'll spread into your work, into your morality, into your entire being... There are NO limits. There are plateaus, but you must not stay there, you must go beyond them. If it kills you, it kills you. A man must constantly exceed his level.” - Bruce Lee

Your  mindset and your limiting beliefs can control your work, your morality, in short, your entire being. So stop setting constraints

Don't get complacent. Dont stop

Go for your dreams, and if it kills you, it kills you.

Cause if you aren't evolving or exceeding yourself time and again you might as well be dead.
