i have nieces and nephews who have extra time so they need something they can(fallback) on .when they get older like playing piano .sumthin they can make some money off of.But they dont want to play piano .
Teach them to be creatvie. Have them make things. Anything, like rock people( go to the beach and get some really cool rocks, glue eyes on them and grass or cotton for hair) they look neat when they are done. Or have them start to draw or paint. Its messy but its fun and they could one day be a cartoonist
