It is easy to comment from the sidelines

Critics are everywhere. No matter what anyone does, how great of an achievement it is, you will have a set of people waiting to belittle them.

It is very easy to be a critic. It takes no courage, no effort and no dedication to say — "Told you so they'd fail". There are people out there who literally wait for others to fail just so they could convince themselves that they did the right thing by sitting on the sidelines. It is also much easier to appear smarter when you are sitting around and passing comments.

But those who failed have experienced life. They experienced the joy of doing something they were passionate about. Even if they don't make in the conventional sense, they put themselves out there, they had the balls to try. It would have been easy for them to sit on the sidelines and give a hundred reasons as to why they couldn't do something. They didn't take the easy route.

This quote from Roosevelt captures the essence perfectly:
“It is not the critic who counts; The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat.”

― Theodore Roosevelt
