Since I have been playing mtt's almost everyday for 14 years, I have some advice that might be helpful. I have noticed that my game changes all the time, but, the most important variable in winning or losing, is patience.
When I am winning it's only because I am patient. Sure I have won playing loose, but overall, loose play gets the best of me most times.
So, if you start out playing and you feel antsy or a need to play too many hands, that's a good day to do something else.
