It’s likely that “success” that you envision for yourself isn’t ready to happen yet. If so, the driving factor is possibly that you don’t know what you value you yet.
There are stories of people who built successful businesses, sold for more money than could be spent in a lifetime and are miserable. Money wasn’t what they actually valued, they just didn’t realize it. Perhaps they valued contributing to something that continued to grow. Or the camaraderie they built alongside their employees. Or the ability to lead people on a significant endeavor. After trading all that for money, they didn’t feel right any more.
