Hiding results from yourself

[AMT]

ive been trying to go through days without even knowing how much im up or down, as i believe this will vastly help my game overall...my problem is i find it virtually impossible to hide $$ amounts or stats from myself while i play. when i buy in it displays my account amount and when i check PT to post hands i cant help but see my ROI/#s right there. does anyone have any suggestions as to how to hide #s from yourself? as i know some players dont like looking until the end of the day/week....
