Doubt of my life

What kind of life I want to be?

Have a house, car, enough money for my lifetime.
Sometime I am doubt of it, is this decision good for me or not.

If I am 29 years old, I would go to Canada to study English for 3-6 months (I had done it in 2006), after that I would go to Australia and others countries for 3-6 months. I want to be a traveler, look around a world.

I am 36 years old now, my next step of my life is have a house and try to save as much as money for my retire, but is this I want, I really doubt of it.
