Question

declamation on trying is better than crying

Answer 1

It's not the critic who counts; Not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit goes to the one who is actually in the arena; Who strives valiantly; who errs and comes up short again and again; Who knows the great devotions, the great enthusiasms, and spends himself in a worthy cause. Who, at the best, knows in the end the triumph of high achievement; and, at the worst, if he fails at least he fails while daring greatly; so that his place will never be among those timid and cold souls who know neither victory or defeat." 
Have you faced defeat in your endeavors? If not, I would contend that you are not putting yourself out there nearly enough. Ask any successful person if they experienced defeat or setbacks along their road to success and you will get a 100% "yes" response". In fact, most successful people have experienced far more defeat than those who are not successful. Most get knocked down once or twice and give up. Successful people get knocked down over and over and over, but they keep bouncing back up and keep moving forward.
In the end, what is worse? Failing, or not trying at all? Which is going to leave you with regret? Which is going to have you wishing you would have tried harder or kept going instead of giving up? Which is going to get you to where you want to go? If you never try, or try and give up quickly, you will have regret down the road. Now I'm not saying there is never a time to let something go so you can move on to something else, but we do it far too often, and bounce from one thing to the next in search of something that will get us to our desired result. But most of the time it is not the "vehicle" that is the issue, it is the "driver" (you). Pick your vehicle that you want to use to get where you are going, and stick to it and make it happen. Don't quit. Most importantly, make sure you are at least out there trying....
