1. Starting the project in a passionate and enthusiastic way (aka STARTING the project at all)
2. Sticking with it!
Let's start with the first idea. If we don't start a project, we'll never be able to finish it. Secondly, if we start a project, but find that we are not enthusiastic about it, we will never be able to find the motivation to follow through with it.
Sometimes, "sticking with it" can be more difficult than it seems. Chores start to come up in our lives, and we find ourselves making excuses for not finishing things that we know deep down we enjoy doing. A classic example of this is the idea of "avoidance", in which we will put off tasks to do other tasks, like washing the dishes instead of writing chapter two of that novel. In my case, it is reading the paper or chewing some bubble gum instead of doing guitar scales. Sometimes I will eat several pieces of watermelon before I sit down and write.
Of course, I'm kidding around, but these things aren't very far from the truth. I've been known to walk around my studio bouncing a tennis ball up and down on a racket just to get the creative juices flowing.
My advice to you all is to sit down and work on your projects while you have the energy and passion inside of you. If you feel like you've tried and tried and tried and you can't summon the energy to do it, you should probably try to do something new. But always stick with it and try to progress through the early stages. Starting is always the hardest part.
