My sister just graduated with her CS degree. She's been working as a part-time coder and part-time graphic designer for my company for the past few years. When I told her she should "get a real job now", instead of working for her brother, she said:
"But I don't know what I want to do in life yet."
Here's the email I sent in response:
Don't think of getting a job as "deciding what to do". Sometimes you just get a job to gain more skills so you have more options. In fact, getting a job is a great way to delay the decision of "deciding what to do".
I learned more in 1 year at my first job than I did in 4 years of college. I doubled my XP really quickly. If I hadn't done that, I wouldn't have gone to grad school and I wouldn't have started a company.
So just do it. You're not finalizing your career. You're beginning it.
