it helps to throw a ton of tricks that you are super comfortable with first without falling; and once you've got some sort of tempo going go out and throw your new trick. For me, when I do a bunch of tricks I know how to do (regardless of how easy they are i.e. simple grabs & 180s) it builds up my confidence and takes the edge/fear off of trying something new. Here's what I normally do when I try something new to get over the fear and has worked so far.
-Warm up- (carve around, use all your edges, surface 180s, couple 1-wake jumps, reentries, get used to the wake etc.) just go out there and have fun being on the water...
-Maintenance Riding- (throw as many tricks that you have in your bag that you are confident with starting with basic w2w airs/grabs all the way up) this builds your confidence quickly and puts you in a good spot mentally to try something new.
-Learn the basics of the trick-
I'll use a heel 3 for example since that's normally the easiest to explain. Slow the boat down and learn your surface 3s first. Then move onto ollie 3s, or inside out 3s, and outside in 3s. There are a lot of good instructionals out there to help you learn the basics so follow those.
-Throw the damn thing-
Speed the boat up and do a couple w2w jumps to make sure you got the right edge/pop for the trick you are doing and go out and throw the thing. Depending on how well you've learned your basics there's a good chance that you'll stick it on this step. If not don't worry... Try a few of these and if you can't make the adjustments right away don't just keep throwing it over and over. The most important thing is that mentally you should be comfortable with throwing the trick and even more importantly, realizing that you're able to do it. You'll also get over your fear of falling on the trick.
This doesn't even necessarily have to be a whole new set, but the point is to go back and ride for a while without falling all the time and hitting tricks that you already know how to do to build up some momentum.
-Stick the Trick-
On the same line, go out and throw your new trick. For example, hs grab, ts grab , hs 180, ts 180, hs 3. HOpefully by this time you'll be over your fear of the trick and it'll become just a part of your normal riding to throw it.
Don't get stuck on any part of these steps. If you're not hitting your new trick, chances are you need to either move backward or forward in the process (i.e. if you've thrown it over and over then go back to the basics or if you've been stuck on the basics forever then chances are you need to go out and throw a few help you progress). We're so lucky to wakeboard at this day and age because we already have the processes and steps laid out before us from our current pros and instructors. All we need to do is to recognize when it's time to move on or to take a step back.
This is just my opinion and it's worked for me. You can obviously do all this in the same set, or between two sets, or two days depending on your natural ability. Just don't get frustrated and don't just go out and huck the thing your first hit at the wake. When you do that, you don't really figure out the mechanics of the trick that way and we all know people are scared of things they don't understand.
