If you're not an entrepreneur with great ideas coming out your ass all the time, then go to school to get a post-graduate degree. If you are an entrepreneur, you need the ambition and drive to put your ideas into fruition.
Surround yourself with successful and ambitious people. If your friends are all just sitting in an apartment smoking weed, playing video games, and ordering take-out, then that's a glimpse into your future.
I was fortunate to have several Asian friends in high school and CEGEP. It was a competitive environment where each one would always try to one up the other. If one became a doctor, the other would go on to become a plastic surgeon. If one got his Master's in engineering, the other went on to get his PhD. If one became a lawyer, the other also became a lawyer, then got an MBA. Had it not been for my ambitious friends, my life would probably be different now, because I didn't come from money, not did my parents really encourage me to become successful.
I'm far from rich, but I'm glad to have gotten a great education when it was time to do so. I'm still young, making decent money, and my field has potential to afford me a very comfortable living. I know several people who are trying to get their Bachelor's degree in their 30s, while working shitty jobs full time, and paying off useless consumer debt.
Set short and long term goals for yourself and do everything necessary to accomplish them. Don't waste money on useless material possessions until you can afford them without any effect on your standard of living.
