how to analyze your games

hello fello chess lovers. i know analyzing your games is very important to improvement but is there a certian way to do it? how do some of you stronger players analyze your games and what do you look for? besides spotting tactical mistake which you normally see right after you make them what should you do? i have fritz and i know that could give me some tactical insight but other that that what do i do when anaylzing?

ok i see what your saying to asseas your strategy during the game. so do you think if my overall strategy was good in finding the weakspot in his position and attacking it(i have never been 1 to wrecklessly attack if anything i play to passive) but i lost because i made a tactical mistake that the game probaby isnt as important to review seeing as i know what lost me the game and going over that key tactical mistake isnt really gonna help me much

i actually have silmans books havent read them all the way through though(read reasses your chess tell right after the minor peices in the middle game part then decided it was a little to advanced for me at the moment, and then i skimmed throught the amatuers mind) which 1 of his books would you recommend?

Basically, at the class level (which many of us fall into), I just go through my games with Fritz 11 and watch for the "stoplight" function to turn red, or even yellow, indicating a slight or really bad blunder.  Once that happens, I let the engine analyze there for a while, and consider what its suggested lines are.  Tactical missteps are going to likely be almost 100% of our issues.
