Gotta Commit to Complete

Classes Attended: 3 Regular, 1 Private

Our coach (or professor if that's what you prefer to call you BJJ instructor) told us (the white belts) something that's really been sticking with me throughout the week. It's something he also reiterated to me during my private session in which I was working on take downs. You have to believe in the technique you're doing. What he meant was that we, the white belts, have a tendency to half-ass commit to a technique because we're scared if we don't pull it off we'll end up in a bad position. Which often leads to not only a failed technique but being put into a bad position as well. So it's pretty much lose-lose, yet I all too often find myself doing this exact thing.
For example, when doing a scissor sweep, I have a huge tendency to leave my bottom leg (the one that blocks against their leg) up at the top of my partner's leg instead of on the mat against their leg. So I'm already in my own way for completing the sweep. Usually I notice I'm doing this after I failed the attempt. And I've come to realize the reason I'm doing this is so my bottom leg is in a better position to prevent my partner from passing to that side. I also have a tendency to take too long to attempt the sweep, often telegraphing it by bringing my knee in and then waiting a few seconds before dropping the other leg before trying to kick my partner over. Both tendencies usually leave me with not only a failed sweep attempt, but my guard being passed as well. And this is really just one example of a technique I have an issue of not truly committing to when the time is right.
After some thinking about it, I've decided my goal awhile (in addition to still making it to at least three classes a week) is going to be just fully committing to whatever technique I think is best at the time. I'm probably going to be wrong a lot and even if I'm attempting the right technique, I'm likely to miss a step or two. But I think in the end it'll help me a whole lot more to be fully committing to what I'm doing instead of worrying about what happens if it doesn't work (there's probably some life advice in this for me as well, but between work, bjj, and school, I don't have much time for a life right now).
