This simple formula Jane shared really put things in perspective for me.
Also it brought me to realise: if someone put effort into making the code more readable and well-structured, then it’s less effort to read / work with later. If someone wrote “bad code” - perhaps spent less effort writing it - it takes extra effort to read later. Either way, the sum of total effort can be the same. No easy way out, the effort has to be spent by someone at some point, always.
