I don't call it pressure, I call it incentive. We're all split in so many directions in this multi-tasking culture that it takes real incentive to focus on something that is not life and death - like paying the rent. That's why I like being part of a group; joining a performance group or a writing group is a "put up or shut up" move. It forces you to focus. Facing the critical looks from other like-minded people move you to get off the fence and into the game (to mix about a million metaphors).
Good for you. Keep it up.
