Cant speak for painting but after a couple of failed attempts to pick up the guitar in my teens I one day started playing what I felt like instead of trying to play some fast hard rock riff, instant success and now I play guitar every day and starting to be genuinely good at it. So, paint what you feel like. Explore other painters and artists and try to copy their work while still maintaining your personal touch to it. Get a mentor or show what you do on some site for showing art, feedback is really important!
