Unfortunately, I have no profession. But I had the chance to acquire a ridiculously large amount of skills from various areas, from writing (10 books self-published on Amazon), blogging, coding (PHP, Objective C, AngularJS and a few other exotic languages like lua), up to reading astrological charts (I generally avoid telling people that I know that, but I extensively use it for myself and my close friends).
Occasionally, the planets are aligning in such a way that I can also make money by mixing one or more of these skills.
A man doesn't need simply one profession if he has the skills to survive applying what he knows to live. :)
