i only have an associates degree in illustration and had to further my skill set on my own and i taught myself how to play [mediocre] bass and the most important thing is consistency. iāve always been told practicing something five minutes a day regularly is better than once a week for two hoursā¦and itās true!
for visual art, try doing a self portrait every day, a plein air painting or sketchā¦ really anything! even if you donāt like it youāre learning and growing. donāt bombard yourself with fancy supplies and remember you have to learn the rules to break them. art history and foundational drawing practice are very important. hone in your skills with line and value and once you master that explore some basic color theory. drawing observationally (still life, models, landscapes) will help you immensely no matter what you decide to do with your talent. if youāve got the budget for it, see if you can take a class at a local arts council or community college. digital art is just as valid if youāre worried about going through materials and a great medium for quick warm ups and practice. youāre really interested in painting, try doing master copies, thatās where you copy an existing work to kind of get a feel for the techniques the artist used and itās completely fine and dandy to do so. i had a professor who would make us do weekly pencil self portraits in the style of various artists and it was extremely helpful in terms of problem solving. art is basically just problem solving with form and color.
as for instrumentally, i had no background in music and no schooling or guidance to help me. i also decided to play bass with no background in guitar which i am told is slightly blasphemous but i just really enjoy a juicy bass line! iām def not perfect, in fact i am quite a wonky bassist, but iām having a good time āŗ research different styles and models of the instrument you enjoy along with basic maintenance and caretaking. do you need any additional materials for this (pick, amp etcā¦)? sort of like the master copies, find a few players of said instrument that you really look up to. i taught myself VERY basic music theory via youtube (that site will be your best friend!) and scales and warmups there as well. once youāve got the muscle memory for all that you can begin to emulate the music you look up to. i would teach myself the bass tabs of my favorite songs, and once i got the hang of them, sort of dissected them to see what makes them work, which helped me develop sounds of my own invention.
hope this didnāt sound like too much! itās hard to comprehensively give advice on this sort of thing as being self taught isnāt a linear thing in my experience. i hope this helped some and best of luck with your creative endeavors and remember having. fun triumphs over all else <3
