One bit of warning when reading poker tips is to make sure you put it into the context of your game. Not all advice will be appropriate for every game and limit. I wouldn't play the same way against low limit players as I would against upper limit guys.
A major mistake people make is to overplay against inexperienced players. All the tricks go out the window when you're playing against someone who doesn't know what they are doing. Examples of this include deception, raising more hands to get value on good ones, slow playing, etc.
The point of poker is to win the chips. Against bad players the best way to do this is to bet your good hands and fold your bad ones -- ABC poker. That's the easiest "hat" you wear in holdem. All the tricks and moves you learn to win at bigger games come at a cost. They add variance and risk to your game. They are necessary because you can't play ABC poker at big limits and win. If you could, everyone would do it. So keep the tricky advanced stuff for the tough games and play solid straightforward poker against the inexperienced.
Oops, I already wrote another tip about this, and here it is:
"Deception is important, but not against bad players. The cardinal sin in poker is trying to play a fancy game against an opponent who is too inexperienced to realize what you are doing. This would be analogous with trying to play mind games with someone who doesn't have a mind. The way to beat a bad player is to play a solid game of showing them the best hands. Anytime you make fancy plays, it costs you something because you aren't playing the hand how it ideally should be. There is no reason to do this against someone who will play who you want them to anyway. The reason why deception is important against good opponents is because if you always play a hand how it should be played, you reveal the strength of your hand, and the good player will likely get out of your way. You use deception as a means to keep the opponent offguard so when you have a good hand, you'll get paid off. The bad player always pays you off so there is no reason to get tricky. "
