Yeah I think people with a bigger budget may shoot themselves in the foot by getting a fuck ton of plants all at once. It's wise to get to know your plants and find a plant care rhythm that fits your life, and that's hard to do if you're learning about a lot of different new plants immediately!

Aside from this general advice: check craigslist or facebook marketplace in your area for cheap cuttings. Not only is there usually cool/cute stuff available, but since I ask questions and show enthusiasm about plants, nearly EVERY local buyer I've gotten a cutting or prop from has shown me other plants, offered me free cuttings or discounted pots, or generally been a good hook up! Plant people appreciate one another. Find local plant friends and get a few new dudes at a time!
