I went to over 15 different kinds of sports, while growing up. I then started playing music and I've been into that for a long time, and love it. For me the key was to feel good at it. I mostly quit stuff because I felt bad and due to my ADD lacked the "willpower" to continue. With music however it was different, because I played with people, and got good feedback. So try paint with friends, or find people with similar interest Also another thing - try to go the art galleries and become inspired. Everytime I felt like I was about to quit, I would go to a concert, and I would get so inspired I could play for hours! Try to discover more subgengres in your area, and expand what you can do with your field! And lastly, don't force it! If you need to take a break, take a break - for me the worst thing that could happen is that I would get so mad at not being able to maintain my interest that I would lose my interest due to that. So try to be relaxed about it and remember you're just doing it for fun Also the probably best and last tip is try to personalize your passion. I write lyrics in music that fit to my life. Therefore it has become such an important part of my life, because it's my way of expressing who I am - and since I develop my music (in your case art) will also develop. (these tips mostly apply to arts). Sorry for my bad english, and long post, but I hope it's useful, feel free to pm me, or ask any questions, have a good day
