Yes, it is true that you control your destiny. Many will argue however what you will find is the ones who actually engage the process and "DO IT" have what they want.
I would recommend checking out the following:

Law of Attraction - Napoleon Hill
Dreamboards are highly effective as well. I was forced to create one a few years ago as I thought it was all non-sense. Well, im a believer now since I kept it out of sight as it was meaningless to me until I cam across it a few months ago and had learned I accomplished most of what was on the dreamboard. This right here is also why I do not believe in luck anymore.
