Prop Making Me Wonder What’s the Investing Equivalent?

I spend a lot of time crafting props taking basic materials and turning them into something unique with patience and detail. It got me thinking: is there an equivalent in investing? Something where you start with humble beginnings, put in the work over time, and end up with something far more valuable. Value investing comes to mind, but I’d love to hear from others. Are there strategies or philosophies that feel like the slow, hands-on process of prop making? Curious what you all think!
