I paint and draw, purely as a hobby. You wouldn’t believe the amount of crap some people have. Brushes they use only once in a lifetime, for one specific element. Special colours they also get to use only once. Pencils they don’t even open. Get a basic set, familiarise yourself with it, stretch it to the full extent of its capabilities (that’s mastery), and then upgrade to a higher quality version of what you have. No single-use novelty tools and materials.
