Dh and I are lawyers and we are trying to give careers advice to a 17 year old dd who is in no shape or form likely to become a lawyer, nor would we advise anyone to but that is a different story.
Both of us are considered pretty successful amongst our wide university peers. We see what money buys and how your chosen career can determine how soon and what ceiling your earnings peak at. This in turn dictates where you live, the size of the house, the car you drive and the schools your dc go to.
I would say look at the people who are successful in your field and how long it took them to get there and how much they earn. In all likelihood, you will not have the same opportunities as they did. For example, if you are in publishing, it is not a growing industry, quite the opposite.
If you want to be successful in traditional terms, you are at the perfect age to take a risk. I would research what are the fast growing fields out there that are crying out for skills and people and do a course or find a job (even at a lower pay) to get into that industry and work your way up.
It may be not glamorous - the most glamorous jobs do not tend to pay well because so many people are prepared to do it for next to nothing - but keep at it. You will get there 
Being ambitious is truly half or not most of the battle won. Then keep reinventing yourself and upskilling and go for more responsibility and senior positions. If you don't get the promotion you deserve, jump ship. Go for higher pay or go for lower pay if it means you get valuable experience. The great thing is at your age, you threaten no one in middle management and are not over-qualified. You don't have dependents or high expenses. Therefore, you can get the job, get into the fastest growing field you can find that makes use of your personality, skillsets and strengths. This could be technical, management, influencing people, or sales.
Seek out people and ask for their experience. To guide my dd, I go on mn and search out old threads or start new ones for careers advice. Good luck!
