Don't brush off a new skill simply because it's difficult on first attempt, this is where the gold is! My wall dribble a month ago was barely anything, I was only able to connect a few solid bumps. Now I'm up to 50! Still need a little footwork but it will come.
Many wonder, why dribble the ball on the wall in the first place? Well it's the new bicep curl of course! Seriously though it's easy to miss the target looking at the tip of the arrow. So much goodness here but for me the benefit is in process, learning how to break down a skill, because it's something that is transferable to any other pattern or learning in life. Of course there's footwork, timing, reaction...blah blah blah. These benefits just happen, and are lovely, but not the sole motivation for the practice. This is the real way to developing longevity and motivation of practice regardless of outcome.
