This is a repository for major, life-altering mistakes that you or others have made. Detailed accounts of specific mistakes are welcome, and so are mentions of general classes of mistakes that people often make. If similar repositories already exist (inside or outside of LW), links are greatly appreciated.
The purpose of this repository is to collect information about serious misjudgements and mistakes in order to help people avoid similar mistakes. (I am posting this repository because I'm trying to conduct a premortem on my life and figure out what catastrophic risks may screw me over in the near or far future.)
I've heard (but not experienced) that having to commute to campus, as opposed to being within walking distance, made people less likely to attend class regularly, and having to deal with any consequences of that. Obviously it depends on the person though. And on top of that, public transportation (at least in the US) can be slower and/or more unreliable compared to driving.
