I started out as a teenager I was a snooker player, or pool player. Through that I met some other teenagers that were gamblers, if you will, who started basement games. I was just sort of learning on the go, losing my $10.
The thing that can get confusing is you think, is this guy really a good player or does he just seem that way based on the way that they are playing. That takes longer to figure out, if they really are a good player or they just seem like one [bad].
If I haven't played with a player before and I don't know anything about them, the more they tell me about themselves, the better I will be able to judge how they think and how they play.
Too many players focus on physical tells. For both online and live games, you should be focusing more on betting patterns and histories. The ability to figure out your opponent's hand based on his betting pattern is a crucial skill.
The majority of players are looking for reasons to fold. I am looking for reasons to play.
