Improving Chess Games

Hello all.  I am constantly trying to improve and learn more about chess each day.  It is in many ways a habit of mine and always like to try win all games.  This is ofcourse is not the case and would like to know what other players do to improve their games.

However, at the moment I play constantly and try to learn openings.  I would like to improve my tactics and end games.  I find that the tactics of chess is interesting and difficult to complete successful.  Being a paying member of chess.com, I am able to use tactics trainer, the forthcoming opening analyser, and Chess Mentor is interesting but I have to pay more to use it.

So apart from Chess.com, what do other members do to improve their game?  What do members do to try and improve their tactics and end games?  Any advice and ways to improve would be helpful. 

What is the best way to analyse your games on chess.com or chesskid.com
