Don't make your goals too vague (e.g. improve health, learn some new marketing skills, etc). If your goals are vague, perhaps these are just proxies for life categories? Come up with specific actions/goals for the vague items.
Don't go to the other extreme, where you have a decent list of very specific things you want to accomplish, but you don't tie it to the broader categories. That's how all your specific goals end up being in one or two categories only. Try to see the forest from the trees.
