A while back, I read about how one's thoughts can affect reality. The technique is called affirmations, and many successful people, such as Dilbert author Scott Adams, swear by them. This method has been around for years, and been published in so many different places that it is nearly impossible for me to give credit to whoever invented it.
Anyways, here is how the technique works. You state your goal, and write it down fifteen times in a row once a day.
For example, if your goal is to have a successful dotcom business, then once a day, you would take pen and paper and write down "I, Ford Prefect, will have a successful dotcom business" 15 times in a row.
Of course, insert your real name, and change the goal to whatever you want. Apply it to your DJ'ing or anything else you desire.
I was pretty skeptical about this stuff at first, but I tried it anyway. To my surprise, it worked! I've been using affirmations ever since to improve everything from my DJ skills to my typing speed. Give it a try. I guarantee that you won't be disappointed.
