You don't have to pick all the dandelions. You don't have to have every ancient seed you find. Trophies that you don't need for crafting or decoration can be left behind.

If you want to play like you are one of Marie Kondo's clients carry what you need to build a workbench and a portal and once you are carrying too much, build the workbench, and then the portal, go through and drop all your stuff off, go back through the portal, dismantle the portal, then the workbench and continue on.
