I'm finding that skills need to be linked together to be of value. Take hopping, for instance.
Hopping on a unicycle isn't as hard as it looks. I'll qualify that: bunny-hopping a few times, not too far off the ground, without moving around much, isn't as hard as I thought it would be. It feels normal compared to some of the other things I've tried to learn. Pedals at 9 and 3, even weight, butt off the seat, one hand on the front seat handle, spring up, bring the seat with you so you can keep feet on pedals, land and cushion with your knees. It feels like I'm riding a pogo stick with very little travel and a very tight spring. I'm clearly still just getting the hang of it. I can do about a dozen hops with right foot forward, same with left foot forward, one hand then the other on the seat (I think I'm obsessed with symmetry). But all the time a rail, pole or car is nearby to support me if I lose my balance. And of course it is tiring.
I know it it will be a useful skill when I come across obstacles I am uncomfortable riding over, but to use it I need to link it with other skills. In other words, I need to figure out how to be riding normally, come to a standstill, hop and then start again. That linkage of skills is still beyond me for now. I should take Megan's advice (linked in an earlier entry) and learn to stall first, and then move on to bunny hops.
