My shaving routine goes something like this.
1. Shave, wait five minutes, shave again due to missing a few patches.
2. Wait 2-3 months for full goatee and patchy sides to grow in
3. Think to self "I'm sick of getting things stuck in my 'stache while I eat," make note to shave that night.
4. A week or two later, actually get around to repeating step 1.
