Writing isn’t a state of mind. It’s an action and like any action, the more you do it, the better you become.
Granted, the artistic expressiveness of writing, especially when it comes to writing jokes, bits, etc. leaves for a huge area of subjectivity as to what’s bad, good, or the best, but the best joke writers we know are writing all the time regardless of whether they are high, drunk, sober, depressed, manic, or have to rudely stop a conversation to jot something down. Even if what they write ends up staying written and never to be said because of how stupid it is, they feel worst altogether if they don’t write.
With all of that being said, in selling your Xbox for weed, you did get rid of a major distraction.
