Educational preparation, which can be college.
If you already know who and what you want to be in your future life, this can effect your future income.
EX: Going to the right college that you prepped for, going to the right classes that you prepped for.
You can get your dream job/life shorter when you are planning ahead.
When you then get it shorter this can effect your income positively.
Obviously you will probably make more money or income when you go to college and knowing what you want in your life.
I hope I helped!
