If you have an idea for something creative, something you have a plan for, something that will take time, but that you plan to dedicate yourself to, then nurture that idea, see it to its completion, even if it turns out terrible. Also if you hear a voice in the back of your head that says its ok to let up for a bit, to go back on what you said you were going to do, then take that voice and drown it in the bath tub. Show it no mercy, it has none for you.
