Always have fun. If you're not enjoying writing something, then there's a good chance your readers won't have fun reading it. Don't ever beat yourself up because you hate what you wrote the night before. You have absolute power and control to change everything and anything! Oh, The Power! ;)
Your technique and voice will develop the more you write, and the more you go back over your stories and edit them. Try out different processes to see how you work best. Experiment! Practice making your stories as consistent throughout as possible.
