In those days immediately after leaving school or college or university we are rather take with the idea of a "good profession", of a good income and, let's face it, what other people say.
A few years down the track, we become more drawn to a career we might enjoy, one that gives us satisfaction, where we might just look forward to getting up in the morning and facing the day.

In my case that meant bankruptcy of my freelance business but, in the long run, it was worth it.
More, it saved my sanity.
