Work with quality

I recently restocked some art supplies and I was reminded that they can be costly but for all that it can be worth it. I think there's a tendency to use cheaper materials because they're cheaper, I certainly did for quite a while. I was told at one point to use better materials and I resisted for a while, after all I was an art student but I've come to see the wisdom in using better quality materials.
Probably the more obvious reason to use quality is that I'm an artist, I want to sell my work, I don't want to have to worry about someone being upset down the road because a painting or drawing wasn't made to last like they thought it should. I work to make my art archival; you see lots of paintings in museums that are cracked etc. and in many cases there are older works in better shape because they were made in a more archival manner, it's sad to see paintings that grow old before their time. As much as I love da Vinci, his Last Supper is a perfect example, that fresco is absolutely beautiful but due to the experimental method da Vinci used, it had issues almost immediately. I've gotten a little off topic but I go to higher quality materials because they have a greater tendency to be archival as well.
Depending on what type of material and how you use it, you might also be able to make it last a long time. I have some watercolors that I got four or five years ago that I'm still using or only recently replaced.
The less obvious reason, at least to me, was the impact quality materials make on your final product, from brushes to paper, etc. I don't remember an obvious right away realization, it may have been when I used some lower quality materials that I was able to see the difference, better quality materials, better quality work.
