The saying goes: it takes ten years to become an overnight success.
As for the stick or twist question, if your only goal is to make money then twisting whenever it seems to make that more likely makes sense. Most people thrive on doing work they care about enough to stick with when it is hard, and my guess is that gets better results over time.
One bit of practical advice: celebrate the little successes on the way to whatever you may think a big success looks like. Wherever the journey ends up, it's important to enjoy it as much as possible.
