1. You submit your first shirt and either
a) You are flamed to death and suddenly begin to think that maybe it was a bad idea to switch your major from business to art
or b) You are given (mostly) nice compliments and begin to feel warm and fuzzy.

2. You continues submitting, but you get lazy/use text , hearts, pandas, drips, etc./try something new that fails/or just suddenly develop an influx of suckage.
Flaming insues and you throw your tablet against the wall in angst

3. (If you didn't give up on step 2) You actually made a shirt that people like. Holy crap! But oops your shirt doesn't score high enough to actually be printed.

4. Continue to alternate between making awesome shirts, and craptacular shirts until you actually get printed or give up in frustration. Enjoy!
