LOL...I changed later than that...

And don't (ever) worry about what others think--the only person you need to worry about what they think is yourself.

In my case, I could have been successful, earned a very nice income--but I asked myself "do I want to be 65 years old still doing this and say -- gee, I wish I would have switched careers back when I had the chance..."

Plan it out (don't be impulsive) but forge your own path - and remember to enjoy the journey itself along the way...
