[ Series / Parallel ]
I vaguely remember my ‘introduction to electrical engineering’ course in first year university. I remember there were imaginary numbers involved, and I remember the importance of knowing if a circuit needed to be in series or could be in parallel. In the first case: one thing at a time. In the second: multiple processes could occur at the same time.
There’s a piece of advice out there that says, “slow down, accomplish more”. That might be true. The one I like better, though, is “Do one thing at a time”. For humans, working in series is better than in parallel.
