Seems like a good time for a lesson in perseverance plus figuring out when to enlist help. Can some things be done by both of you together and others be done by him (like the painting) with some encouragement and letting him know it's normal that learners don't always get it right the first time and may have to do it twice? It can be hard for a kid to realize that he doesn't have to be perfect from the get-go when he tries something with Dad watching.
