Oh don't loose heart... Makeup like any art-form is a bit of a skill... some people are naturally talented and take it to levels that really are just pure art...
Most of us, however, do not have such talent.. and we just practice and work on it until we get something that works for us, that we can probably repeat over and over...
So, if I was you, I would consider your first make-up as the same as your first box of watercolours or something.. Know you are going to make a mess at first.. but have fun doing it.. Pick one thing you like the look of and try doing that.. an eye shade, or a lipstick... you can easily take it all off again and start over...
Eventually you will find a style you like that you can do for everyday and a few tricks that will spruce it up for the more glam times... but... importantly.. don't stress it, have fun....
