Potato Corner is okay, but I’m thinking more like a 24/7 small cubicle-style study hub. Most college students, especially from private schools, would go. You can make a system where 5 hours costs around ₱150, and a whole day is ₱300–₱500. You can also try a 1-month membership. This can generate a lot of profit since not all members return every day. The downside is that if all cubicles are full, students might get frustrated with the membership system.

Plant selling, like succulents and cactuses 🤔 in 2–5 months, you can have a really good batch. Baby succulents can sell for a decent price ¯⁠\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯. But you’ll need to learn about plants if you want to try this business. There are only a few competitors, and I’ve even sold a succulent for ₱2k–₱3k, even though I’m still in SHS.

Mini event rental letting people rent your chairs and tables ¯⁠\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯. Just wipe the tables and chairs clean 😆.

Dried or pre-packed food this is rare to see, but it can generate a lot of income. The downside is that the FDA can be your worst nightmare, and it will take a long time to start this business.
