Also: accept that what you make is ephemeral. No one pauses in the middle of building a sand castle on the beach and wonders if their sand-sculpting skills are adequate. Anything you make, even if it becomes one of humanity’s most cherished works (extremely unlikely!) is not going to be here for very long. So enjoy the process, put it out in the world, and maybe a person or two will appreciate it before the waves wash it away.
