You are so right on what you can learn from mistakes. Even though they are scary they will give a learning experience you cannot find anywhere else.

I can sometimes be jealous of people that have found a passion early in life, not that I never had any but after trying a lot of different things I found mine quite late. Now I have the feeling that things are slowly starting to develop (I am 27). Also I am going to be taking a big leap in the next month to go work and live in a different country. Stuff that I wish I had done way sooner. But hey, as you said... It's all okay, there's no point in regretting anything in life!
