Taking a break

I have been working in the IT industry for almost 13 years. Last April I decided to take a break. I quit my job and decided to stay at home with my kids during the summer. The idea was to start looking for a job once the summer is over. Also during this break I thought I would get my priorities straight and see if I want to do something else all together. I have a bunch of ideas in my head but am very scared if I will fall flat on my face if I try something new. I keep telling my kids to just dive into things to know the depth of it but I myself have always been scared of trying new things. I keep reading articles on the internet and motivational quotes about how you have to try and fail before you succeed and all that. But somehow I can't gather the courage to get something started.I just wanted to write my feelings out to see if it makes any difference.
