I Need to Remember This

I had to write this shit out on a post-it note. I keep forgetting it, and it’s driving me batty. I need to ingrain this so that it’s second nature.

? = zero or one
* = zero or more
+ = one or more

I swear, if I could get away with it… I’d write it on my monitor at work. Permanent marker. Right below the screen, near the buttons.
