There’s very little you can’t do with what you already have. In fact, you’re probably better off simplifying and doing more with less. If you want to write, and you need a fancy new Italian journal before you get started, lacking a journal isn’t your problem. If you want to be an artist, you don’t need the best paper or brushes, all you need is a surface and something to make a mark. Writers have been writing masterpieces on the backs of envelopes and receipts for centuries; world-shattering art can be created by simply signing, per Duchamp, a urinal with a pseudonym.
It’s nice to have the best tools, and when a difference needs to be made, they’ll definitely make the difference. Professionals almost always use the best tools available because that edge is necessary to remain competitive. Give a brilliant photographer a shitty disposable camera, however, and they’ll take a brilliant photograph. A real artist is a craftsman (the reverse is also true), and understands the strengths and limitations of the tools and materials at hand and how to use them to their advantage.
There are practitioners in every field who are focused on the accessories rather than the work. To them, status and acquisition is more important than accomplishment.
A real artist can create real art with anything, no matter how humble. Some of the most transcendent music ever recorded was played on second-hand, second-rate guitars with high action and boxy tone. Some of the most important art ever created was made by scratching lines into the wall of a cave with a rock.
