Mind power

Following my earlier posts. Life, what is the meaning? And is it possible for every person to live the life they have dreamed of? If so what is the one thing that will make sure we live the lifes we want? Because when you look at nature you never see trees on one side of the road with no leaves and the trees on the other with leaves. They all either got leaves or not? So it begs the question if a person never lives the life they want who is at fault the person or life?

Because I've once heard a man say the man with the most flexible mind wins.

If this is the case then are we really in control of our lifes?
