1. Move down. Unless money is of no value you can learn while losing less until you turn the corner to profitability.
2. Don't multitable until you can win at one table consistantly. If you're making bad decisions on one table, you will probably make more if you multitable before you're ready.
3. Patience. I sometimes right this down somewhere before playing. I'm a winning player but this is one issue I constantly struggle with.
4. Study/read/think. Don't think that just by playing alone you will get better(though that is important)
5. Stick to one game for now, either limit or NL, and either ring or SNGs. Once you can beat it, only then move to something else
