Anyone else have this problem.

So, I've been surfing once or twice a week for about 3 months now. I have gotten to the point where I am comfortable popping up and riding waves but only when I'm on the shoulder with a clear lane.
If it's a bigger wave and rolling over too quick I can't seem to force myself to pop up. I see everyone else having no problem popping up when it's closing out and then doing a bottom turn to get in front of it. I don't know what it is. I went out today and was positioned perfectly on the shoulder a few times, but it was peeling off pretty quick. By the time I went to pop up, it was already curling over and I just bailed off when I should have just stood up and took it. For some reason I just see a wipe out in my future on waves like that and can't force myself to take it.
Anyway, I just wanted to see if anyone else had this problem when starting out and if so, how you got over it.
