1. Covering your basics (such as reading, writing, and math) will get you a long way. After you know the basics, you can look into options. Join a company that will let you learn different and transferable skill sets and be a master.
2. Market analysis - Understand what professions are in hot demand right now
3. Passive income via hobby/passion - You never know how far this will go
4. Be a trailblazer and look into new products/areas/industries/unregulated space - For example, crypto is new and exploring that can be risky, but high-risk high rewards!
5. Personal finance - Invest your money early! Own equity (start your own company, join a start up and get equity, buy equity). If we look at the richest people, they all own equity!
Software, medicine, law, finance, etc
1.) In the world of work ---- Education and Experience
2.) In the business world ---- offer a Product and/or Service people want or need.
You must bring VALUE to someone else before they will "give" their money to you in exchange.
For all the other cases, that is the majority of all of us; the way you can make a profitably career is hard work and a good preparation, developing soft and hard skills that you need to thrive in the professional world. There are some fields related to Finance, Computer Technology or Engineerings that could have better salaries.
One personal recommendation is that you need to find a career that will fulfill your life, if you only want a lot of money but you do not enjoy the way you are achieving it, maybe it could affect your happiness and mental peace. I wish you all the success for your career.
"A lot of money" is somewhat relative. First, determine what a lot of money means to you.
Determine what sort of lifestyle you want to live, what sort of charitable contributions you want to make, what area you want to leave in, how much you want to save for retirement and based on that determine a minimal amount of money you'd need to make to meet your own unique life goals.
Once you have the minimal amount, look up a site (there are plenty) that give approximate salary ranges for various careers.
Look at the careers that both interest you and meet your goal.
Once you have a career to aim at, search for colleges with majors that support that career.
Study and learn and when you have a job, always do your best!
Good luck :)
