Is life mostly a matter of chance?

No: it's a matter of decisions. As soon as we are able to think for ourselves we probable make over a 100 decisions each day. Our life is controlled by those choices we make which is derived from a decision which we are often constantly and often unknowingly bombarded with. Of course there is no question that our DNA will bring about certain problems and certain greatness, we still make decisions even if or genetics lead to some type of cancer. After all do we decided to go have a regular checkup, that could alter the genetic deposed cancer??? Sure we do. I've often thought about writing a book called "THE POWER OF DECISIONS'.
