Laugh at your own jokes when you’re alone. If they’re funny to you, that’s one fan already.

Your own taste is the only audience guaranteed to be there. Waiting for a laugh from someone else before you decide something was good hands the verdict to whoever happens to be in the room. Enjoying your own stuff is not arrogance, it is the baseline that keeps you making things at all. Everyone who makes anything started as the only person who liked it.

Notice whether you check faces before letting yourself find something funny. Try not checking once. Keep the joke, the drawing, the idea that made you laugh in an empty room, because that reaction was honest.
