Is there an online skill that takes a long time to learn but is easier to monetize once you're good at it?
I'm not looking for a "get rich quick" skill.
In fact, I'm completely fine with spending months learning something difficult if it creates better long-term opportunities.
My ideal situation would be a skill that:
Takes time and effort to master.
Doesn't require a huge upfront investment.
Can be started with a relatively small budget.
Has consistent demand.
Doesn't require constantly chasing clients just to survive (for example, because of repeat clients, inbound leads, or building your own assets).
I'm curious what skills experienced people would recommend and, more importantly, why.
I'd love to hear your real experiences.
