I once knew a guy who played online poker 16 hours a day. He played about 10 tables at a time all SnG with a range of 18-45 players. He figured out that if you play just one tournament at a time playing correct perfect poker you won't make any money unless you already have a huge bankroll to begin with. But if you play in several tournaments with smaller buy-ins then the amount of profit would increase. How he came to this solution After playing for long hours he realized that the small amount of income he made was not going to pay the bills and he might just consider getting a job like everybody else. Instead of applying for a job he decided to change his game around. He would take his $50 buy-in SnG and go down to $10 buy-in SnG but, instead of one going he would have five going at a time. He realized that by putting all your eggs in one basket the risk of getting out drawn is more costly which means that your not getting paid by the time you spend playing. By playing many tournaments you develop a profit rate that you can rely on. (ex. rate of 15% per hour)

Anyways after a few months of this method my friend could play several tables at a time and was able to go back to playing $50 SnG but playing ten tables at time. If you aren't already I highly using recommend his method. Good Luck at the Tables!
