My opinion, now retired after 40 years in electronics as a design engineer and 10 years as a technician before that, is that "doing circuits" is MUCH more fun as a hobby than as a way to earn a living. Professional accomplishments can be very rewarding, and I've had more than a few; but the satisfaction is tempered by having to put up with corporate politics and bad bosses.I took the right road to keep it at my own personal hobby, and not pursue it any further than that.
Just my opinion; others may differ...
