pick up a hobby - preferably one that you can do while trading. For example, I just starting playing the guitar a few months back. If my system is flat and the market conditions show no indication of a trade coming up soon, I'll just pick up the guitar and start playing.
I would imagine that you are the type of person that needs to not only feel a sense of accomplishment, but also requires the pursuit. If so, pick up a hobby that you would have to try to get good at.
