what we like and what we need....

Inevitably, when it comes to training, there are aspects we all enjoy more than others. However, we all tend to suffer through the areas we don't like as much to better ourselves all around.
I'm not a fan of weapons (defense I appreciate, but I'm talking about weapons for combat). That said, I often find myself practicing with them.
So here's how I look at it:
- it could happen that in desperation I pick up an object to use in a life or death situation.
- it makes me better understand the attacks so I improve my defense in the process.
- it can't hurt my coordination skills.

I guess this is how I spin it, anyway.
Kata is another area where I do this sort of reasoning with myself. A bit of kata I think is valuable... I think we all can figure out reasons why this is so. However, I find too often I get bogged down in so many forms of it that my head spins like a top.
But what if I only practiced what I like? Would that improve my skills to the level I want them to be at? While sometimes the answer feels like it should be yes, I still trust my teachers, and try to focus on the good that can come from doing the things I don't enjoy.
