I've really gotten used to new-school game design.
Whenever I play a lengthy RPG, my mind immediately goes to "I need to find the bank so I can store all of these cool items." I went through around 15 hours of The Outer Worlds before finally realizing: "oh, the world is my bank."
Don't make the same mistake! As soon as you get to your ship/hub (roughly 15 minutes in), use the lockers near the front door to easily store some of your key items. Naturally any stash point will do, that's just one you're going to be fast traveling to a lot.
