How do you solve chess tactics? Do you just grind them, or do you save some of the chess tactics that you miss?

Do you ever annotate your chess tactics?

Do you try to remember certain patterns and main ideas? Do you categorize your tactics by forks, pins, zugzwang, etc.?

How do you recommend we train tactics puzzles?
Training chess tactics should be done by theme. This means solve a set of tactics that are based on a similar theme, like Double Attack, Discovered Check, Absolute Pin, Relative Pin, Skewers, etc. This impresses upon the mind the ideas of that particular kind of tactic and gets your brain looking for it as a matter of course. After, you will find yourself 'seeing' these tactics (i.e., imagining) in your games or at least considering them as a means to an end in your positions. This is the creativity you cultivate in your chess game.
