I don't deal with it. I just believe my code is trash and everything is trash and as long as it works well and noone has to touch it, it's fine, so I pay extra attention to making my code work well for sure. I pay extra attention that it can be hosted on literal potato and I do a lot of defensive programming. Also every single crash dings my e-mail box so I for sure notice if something goes wrong.

I know Im far from perfect but that's how I deal with it. I believe Im at least good enough to do my job.
