You do things when the opportunities come along. I've had periods in my life when I've had a bundle of ideas come along and I've had long dry spells. If I get an idea next week I'll do something. If not I won't do a damn thing.
All I try to do is as earnestly and as acutely as I can conceive a character and try to portray this character just honestly. If the humor is within the absurdity and the awfulness of situations then let it be seen that way.
