If your a losing player the solution is quite simple.
1) you read everything on this site making notes as you go
2)Buy a book like sklansky or harrington. Read it make notes.
3)go to a nice big site with cheap sngs. Play the smallest and learn to beat the game by being tight and playing psoition and stealing the odd blind. (make sure you are adequatly br'ed for these games)
4)Now start to take your game to the LOWEST cash tables you can find. Play the same game tight but now include a few more hands that are a little more unorthodox.
0 (the most important)) Always study your game and figure out where you went wrong. Post hand histories here so others can give you ideas on how to play. Watch players who are winnning money and try to incorporate some of their play into yours. adapt.

This might help, its how i did it. I recomend sngs simply becasue you only commit a fixed amount of cash to a lot of hands (hopefully) therefore you gain experience at the cheapest price and learn about the game.
p.s If your bored playing at one table you are not (i repeat) ARE NOT paying enough attention to the players around you. This speaks for itself if you are losing. Don't multitable until you get good. BE PATIENT
