As an overarching, vague, and obvious comment, but nevertheless worth
emphasizing, watch out for both excess generalization and excess
specialization. As long as it doesn't compromise the medium/long term
in a relevant way (and often it doesn't), doing the simplest thing
that solves the real problem at hand tends to be quite fruitful.
