Step 1: Pretend to be a hermit
Lock yourself in a room, or a closet, or a cardboard box. It's not ideal, but it's a start.
Put on your comfiest pajamas, and a pair of slippers. You know, for comfort.
Order pizza, and a six-pack of beers. You've earned it.
Now, watch cat videos, or reruns of 'The Price is Right'. Anything to avoid human interaction.
Step 2: Pretend to be a hermit (more seriously this time) Step 3: Scream at inanimate objects (optional, but recommended)
