Some good advice already but I want to add..

Ask yourself: why am I playing? To have fun? To win money? In order for you to win you must change your attitude: its no longer about having fun, making money has to come first. If you look at the game as a way to have fun you will consistently lose, IMO. Go to play money for that. If you want to make money you first have to decide that you are playing for that purpose and prepare yourself for it (reading, studying, watching, etc.) Once you make this mental switch, you will no longer get bored and you will have the discpline it takes to prepare yourself (by reading and studying) and to play a correct strategy.
