I have lived quite a long time. That just means I am old, BUT that never stopped me from trying something new. I may not achieve my effort the first time, or the second, or the third, and maybe ten times more, but I don't quit.
Now believe me, I am not the model of a success story. Many things I have tried I never succeeded at. I never was good at sports, except maybe boxing for a short time. I write because I like to, but I am not great. I was a firefighter for more than two and a half decades, but I think I was average. Now I build cars, but I am sure I could get better. I hope I have been a good father and husband, but again I could be better. There some people that a good at (almost) everything they try. I am not that. I do take pride that I tried and never qit at anything I wanted to do.
I believe everyone has a purpose in life, to do one thing really well. Some can do several things well. And we envy them for that. We all wish we could play great baseball, or run a marathon, or act in Hollywood, or write a great novel, or paint an impressive painting that people love. Maybe, just maybe you could if you try, and try, and try over, and over again. Failure are the stepping stones to success. As one person told me, "Anyone who has not failed hundreds of times and give up, will never succeed their dream in life." And Einstein said,"Without failure, the sweetness of success, will never be tasted."
No one likes failure, and everyone love success. But one does not exist without the other. I know people now that are afraid to try new things because they are not sure about themselves, or will not take the time to try. Of course we have to proceed with caution, but if you can not bring yourself to take that leap and have confidence in your abilities, well, then that honey of success will never reach your lips. Failure makes you stronger and builds that confidence IF you let it.
There are other factors too. You must listen to the people who encourage you, who give you hope, and support you efforts. No someone calls you a loser, or beats you down with words of despair. I was lucky to have a few teachers in high school that stuck with me when I tried to reach a goal. I always wanted to be an artist, and my art teacher really encouraged me to keep my creativity going as I improved. She was just one of the people let guided me to try and never quit at no matter what I wanted to achieve. I never became an artist, but I did put the artistic ability in to other dimensions and skills.
I think you should be proud of your failures. That is just a sign of a strong person. Everyone loves a winner, but we should also root for the loser to win the next time. Losers will eventually become the winner and taste that honey. I may have not tasted the honey all that many times, but when I did, it was SO-O-O sweet. Take care and stay safe.
