In the darkest of days, I discovered how to remote login to my computer at work through the company vpn. I then proceeded to work overtime at night in secret for a week or so, writing documentation and refactoring code.

I finally woke the fuck up and realized that I shouldn't be obsessing over proprietary codebases that do not belong to me, and I should put this misguided energy into my own projects.

So yeah, as a bad dev habit I'm working on fixing, this fits the bill.
