Try playing the "Double or Nothing" games. You start with 10, play down to 5 and whoever is left doubles their investment. I find it the least stressful way to make a buck. I worked my way up to the point that I now play 13 x $10 tables at once, takes about 45 minutes (NB - You have to work your way up to this, do not try this at home, yet), and make about $1000-$1500 a month in my spare time, not enough to live off but good beer money or useful for paying unplanned bills. A lot of people do this and the usual win rate is about 56-58%, and trust me even when you go through streaks when you win 80% of your games, you run into pocket aces again and again and again and your win rate drops back to 57%.
Also remember, do not play for serious money until you have played 250,000 hands.
