Regret's a heavy burden to carry. So wouldn’t you rather try and say “oh well” when it doesn’t work out than not giving it a shot and looking back with the regret of “what if?”
You'll go the extra mile just to make sure your phone has a full battery. So why don't you treat yourself the same way? Because you can't perform your best, make the most of your days, or achieve your goals consistently running on empty.
Take a leap of faith. Take that first step and put yourself out there. Because you never know what can happen until you start. Bet on yourself because nobody else is going to do it for you.
Your experiences, personality, character all makes you unique. And that's something that can't be replicated. Realize that your only competition is with yourself... and then start living like it.
