Brian, here's one suggestion, you may, or may not like it.
Restrict yourself to a maximum number of trades per trading day.
Set a max and DO NOT exceed this number of trades.
You can paper trade after you have executed the max, but no real $$$ trades.
This may make you take only the very best trades, and more importantly stop you trying to 'get even' at the market.
As to the max number, start with something pretty low, say three trades.
