Depends on what kind of an engineer you are. :-) I've always been the tinkering kind, myself, but mostly because I'm not smart enough to be the other kind... I worked for a guy way back in the 1970s (pre-PC days) who would sit down at a nice clean desk with his HP calculator and an engineering pad and pencil, and design a complex analog discrete-transistor circuit without once using the eraser. Then he would write out the voltage, current, frequency response, and gain figures for the circuit on a second piece of paper. These he would hand to me to build and test. Always came out dead nuts. Amazing. But a tinkerer? Man, you did NOT want to let this guy get anywhere near a soldering iron! Extreme danger to self and others!!
