Is it not to late to take one more course when you're in quarter-life?

If the purpose for taking such education is just for the sake of learning, then it is good. But if the purpose of such education is to make yourself wealthy, I think it may be too late.

I don't think it is ever too late to take a second course as long as we are still alive. I am actually considering taking up a course entirely different from my line of job. But since I am currently working, I might take short courses for the meantime. I can't afford to stop working and study full time. I guess after years of working for a certain industry, you tend to get weary and you start looking for something different. People always say that learning is a never ending process
