My top tip, in all things, is 'give it a go' !!!!!! I have wasted far too much of my life waiting to be better prepared to embark on projects. The person whose tip was to aim for perfection would be my nemesis. No surer way for a beginner to bleed all the joy out of a new experience than to get hung up on that one. I always try to do something to the best of my ability, but aiming for perfection is just a path to constant disappointment and negative feelings about your own creativity and skills.
