A positive way of living life

I once read a phrase that changed my life, in that phrase it was reduced the way I think life should be lived.
The phrase was the following:

If our dominant thoughts are constantly focused in obtaining positive results,
in our strengh or in our habits of success (and our actions re inforze that
way of thinking) then, that would be what we are going to manifest in life.

This is is a sentence I totally agree, living in a positive way, thinking always positive and doing things, will do what we make in something we always dreamed of.
