Whether you win or lose, your quality of gambling should be the same.
If you are making positive EV plays, then you'll eventuall get what you deserve.
Positive EV or not, have a realistic expectation, then keep it whether you go on a win streak or a losing streak.
I think I've seen more gamblers get ruined because of a win streak they've had than I've seen get ruined because of a losing streak.
In both cases, emotions tend to short circuit rational thinking.
It's a tale as old as time.
