Some people dare to change their socks and some people dare to change the world.
It takes all of us. Reading history after a while you say to yourself, "Why didn't that guy just ease up a little bit and enjoy the sunshine? Have a nice day do nothing but smile a lot." Oh hell no can't have that. If every man in the world stayed home for a day and did nothing much that would be the one day in history there was world peace.
What kind of personal goals do you have? That is a good place to start.
You say you have done a lot of things. Sometime nothing is really good for you it works out to what can you stand for a while? I agree with hoichi really. When you are young it is good to get out and about and do different things enjoy your life. What ever you do for work figure on working harder at it than the people around you.
