When you play, just actively try to snap onto each note, even ones with small spacing. You'll find that it eventually becomes very natural to do once maps start to have bigger jumps in quick succession.
As for improving aim, I guess you should probably try to challenge yourself and play maps that are hard but not hard enough to get less than 95% in (or something along those lines).
