Achieve self-mastery over your thoughts, and constantly direct them toward your goals and objectives. Learn to focus your attention on the goals that you want to achieve and on finding ways to achieve those goals.
The one and only thing over which you have complete and total control is how you focus your own mind. Luckily, this determines everything else.
Remember that your dominating focus attracts, through a definite law of nature, by the shortest and most convenient route, their physical counterpart. Be careful of what you focus on.
