On my way to the city

I am waiting a train to the city. I don't know what I'm going to, neither have a plan. I just wanna go for some reason.
My life is like that: unpredictable. My age is going to be 30, and I should turn new chapter to write new story. However, I have no story to start the new chapter. Ten years of cooking career is good enough to concrete my career because I still feel as if I got lost somewhere. Just because I spent one third of my life to cook, I want to keep doing what I do, yet all the time I questioning myself if it is really I want do to. Simply following order from the big chef isn't surely what I am best at.
I think I am very individual, who doesn't cooperate with others. Another hand, I love to do things together with others. Perhaps, I probably have a good balance between being selfish and people person, I don't know; just like what I absolutely want to do for my life.
I desperately need something that turn my life to new chapter. It can be as similar as looking for a needle in the sand, but I have to find it.
