"Don't let the fear of the time it will take to accomplish something stand in the way of your doing it. The time will pass anyway; we might just as well put that passing time to the best possible use."- Earl Nightingale.
Too many people put fear first as the first leg forward when they have something o do. They wonder "if" they can achieve their set goals and that moment, they put every of their energy into building the fear factor in their lives while leaving to fizzle away their dreams.
Have you heard of the saying, "Time waits for no man?" Well, irrespective of the actions you take or don't take, you will never be able to put time on hold. It ticks even when you are not ready for it to.
So my thought is quite simple, instead of waiting to see if you will win or loose, "fail forward".
Don't spend valuable time thinking about what should have been or what may be, spend that time you have grinding because it is the only best thing you can do whenever, however and wherever.
Fear is a good thing because, it is in place to test your resilience and also your belief in God, deities, hand made effigies or some imaginary forces.
Fear preys on your intelligence or the lack of it and only through you adopting a systematic approach to checkmate it, will you truly overcome and ride on the clouds of your dreams.
For what's worth, just go ahead and do something. Utilizing the time you have with you will help you form an understanding of where to go, what to do, how to do it and although results are not cast on stone, you will either fail or win.
