How did it all start

I believe that life is always showing you what your next step should be. Just don't forget to look around and notice small clues.
A lot of things are circulating in my mind. Some of them will never go further then one-night-insomnia-thoughts. However, I do have them all inside my mind and thus they are boiling there for many many years.
Several things I was discussing with myself are:

- What is really important in one's life?
- Why do we do what we do?
- Which path to choose - where you do what you have to do or where you do what you like to do?
- How to follow your own way?

But I think it really started when I first read a parable:

A black man is lying under a banana and sleeping. Sometimes he wakes up, stretches his hand, takes a banana, eats it, rolls over to another side and continues to sleep.
A white man comes to him and asks:
- Why are you lying here doing nothing? You could take a banana and sell it.
- Why?
- You could plant one more tree then.
- Why?
- Then you could have a banana plantation.
- Why?
- You could reap a good harvest, go to a market, sell it and get a lot of money.
- Why?
- You could hire people to work for you. And then you could lie under a tree and rest...
- And what am I doing now?
