I don't know how many people can actually say they have tried and failed to live their dreams. Most of them did not overcome the fear factor. It's great to see that you have done so many things by now. I find your post inspiring.
Everything is trial and error. I failed so many times but it never stopped me from trying a new way to make my dreams come true. I even wrote a poem called "Failing" lol
It's never too late to try something new. I never understood how some people can simply say :"I am too old to change or try that thing!"
