that's how I got my start! I had a huge desire and not much else, well patience, I have a lot and use plenty! Don't put yourself down and give yourself plenty of time, it will all come to you...however....... if you're "jumping around like a fart on a curtain rod" as my husband says it may take you longer to get it. I like to do lots of different things too but each one needs dedicated time to learn. Once you learn them then you can multi task on work on several at one time.
Well I hope it's a wedding you plan and not the other but I certainly understand, I'm on #3!
Good luck in all your endeavers and welcome to the board.
