bjwedes said..And remember it's all about having FUN
Laughing at yourself and seeing how having a go at doing something that's a challenge has endless rewards
The fact that you are doing something with your kid(s) and their friends will bring you untold connections
Absolutely priceless..

Great response, people often forget that pleasure is the reason for doing things like SUPping.
Mr beast surf, take your time, keep trying, watch some "How to" vids, and above all enjoy yourself.
Master the flatwater first, learn your skills such as turning and then progress to the surf.
Remember that the ocean is constantly moving and you have to adjust for it. Keep your knees bent so you can use them as a shock absorber, keep your paddle in the water - this is your outrigger for stability, keep moving - like riding a bike. It will come to you but it takes time.
Like the others have said Have Fun.
