You can always learn something new. You’re never too old, you’re never too short on time and you don’t have to spend your whole life doing it to be good at it. You only need 20 hours = 45 minutes a day for a month. Pick up that guitar, paintbrush, harmonica, drum, camera, keyboard, game controller, book, knitting needles or whisk and enroll in an adventure of autodidactic learning from your very own home. We all have the ability to teach ourselves, it is what we have been doing our whole lives.
