Multiple times I have found satisfaction and joy in reading non-fiction or how to books about a certain topic and then deep diving. With a library nearby you can avoid spending any real money. Almost every book about a topic has other books as references or recommendations which leads you down a hole of information about things you can learn about and implement. I am currently deep into a research hole about plant identification, herbalism, wild food forging and permaculture. This is great since I can then implement these in my garden this spring but I enjoy the learning part just as much as the doing. Its a fun way to see what interests to you. It doesn't have to last forever but you will keep the knowledge
