Thank you very much, after graduating from university I definitely started a company, but it would always be nice to get the money earlier.
My advice would be to focus on skills and experience. I would happily take a job with a great skilled team and less money working 8h day instead of earning 200k+ a year working 14h a day in a messed up environment - yet still: A good balance is important. A great team earning < 20k a year is also bad.
Keep in mind: In your early career phase nobody (not even good customers) will pay you a fortune without an exceptionally great idea, great planning and a good portion of luck. There is a lack of trust... you're unknown, hard to assess, etc.
Building a stable and growing career based on knowledge is much "healthier" (literally) - less up and downs, more stability, more planning (instead of having luck). Earning too much money too early can cause great damage to your life.
