Joy as I know it is all in the Hands. If you keep your hands busy, you will get more joy. Making things or drawing things is the way to be happy.
I draw pictures with pens and pencils every day. My hobby is a gift from God because I have two working hands to keep busy. If you're playing a guitar or building a test rig for experiments, the joy is the same.
Sometimes I watch videos on YouTube of people building things. I watch other guys build all sorts of things, roller coasters in their back garden, home aquariums and ponds, test rigs for experiments and things like that.
Use those God given gifts, make things with your hands or use your working eyes to read books. All those things can bring joy.
