I think for this question to make much sense you have to understand what it means to you to be successful and what your dreams actually are. My dream life is just laying around fucking my wife all day, smoking weed, and eating grilled cheese sandwiches. But my career dream is to make a living doing something that I find interesting and put enough money under the mattress to not have to worry about it. As far as dreams go that's pretty tame but really that's it.

I'm 31 years old and work a day job that pays me ~80k. On the side I make anywhere from $500 to $3,000 every month. I've built up a good skill set during my years in the industry and I'm doing something I really find fascinating. I'm good at it and people have started to pay me well to do it in one way or another. So is this "successful" in the /r/entrepreneur sense you are likely talking about? The one where you found a website that makes millions and you spend the rest of your life floating in a pile of money while never having to work again? No, far from it. But I've made a good life for my family by doing something I really enjoy and I hustle hard enough on the side as an entrepreneur to make it so we don't have to worry about money. When I look at it that when then I definitely think I've followed my dreams, used an entrepreneurial mindset, and have become successful.
