It could be everything. Or it could be nothing. You keep putting one foot in front of the other, and then one day you look back and you've climbed a mountain. It will keep you cramped and insane your whole life, and it is the main obstacle between you and a shitty first draft. Don't be too timid and squeamish about your actions. All life is an experiment. The more experiments you make the better. Perfectionism is the voice of the oppressor, the enemy of the people. The truth is that you will die anyway and that a lot of people who aren't even looking at their feet are going to do a whole lot better than you, and have a lot more fun while they're doing it. One swing set, well worn but structurally sound, seeks new home. Do not wait for the last judgment. It comes every day. No matter how hard you kick, no matter how high you get, you can't go all the way around.
Warm Regards
