I wouldnt worry about all the intimadation crap Darc, for starters just find some broken shallow beach break waves.
Shallow, knee to waist deep so you can stand and control the board easily.
At first just stand in the shallows and when the white water gets near push forward and jump on the board and let the wave push you.
If the wave passes you, you havnt pushed forward hard enough.
Once you get going on a wave, push up with your arms and arch you back.
Do this a few times just to get used to what you have to do.
At this time you are close to standing up.
Now you have to work out what foot farward you are. You need to do this before standing of course. To work this out is easy, if you ride a skateboard you already know. But if you havnt stand up straight and get someone to push you forward, which ever foot goes forward first is normally the one, right foot goofy left foot natural.
Thats some things to work on
