Bummer about spending your life doing something you hated......


I should have been an engineer - and - have just finished
auditing a semester's worth of classes at the local college.

Passed it all (Pass/Fail grade only) and loved designing
MOSFET and BJT amplifiers; but had a tough time with poles
and zeroes....




Maybe you should have been...might have injected some logic into your
problem solving methods.
Those labs & report writing can have amazing influence.

Suggestion:
Stick with ME courses....more applicable to DIY home repair.
Though, welding, wood shop & basic electrical would be more helpful.

Tip:
Systems are unstable when poles are in the right hand plane.
