Entrepreneur

Keep in mind my favorite quote, by Teddt Roosevelt:

"It is 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 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."

You aren't a failed entrepreneur, you just haven't succeeded yet. 35 is still very young. Most successful business people took several times at bat before hitting a home run. You have time for many more times at the plate. Ignore those booing from the stands, who are rooting for you to fail. They are a sad, pathetic losers, who want you to be a sad pathetic loser, too. Focus on those who are cheering for you.
