I once set an S3 lifecycle setting that accidentally affected 3 years worth of logs to Glacier. The next morning I woke up to a billing alert and an AWS bill with an extra $250k in charges (our normal run rate was $30k/month at the time). Basically I spent my entire add annual cloud budget for the year overnight.

Thankfully after an email to our account rep and a bunch of back and forth I was able to get the charges reduced to $4,300.

Don’t invest in crypto.

That starting the work is half the work. I wasted a lot of time procrastinating, it took me shamefully long to realize that if I could just start an activity for 5 minutes, taking it to completion is then relatively easy

Art school isn’t worth it, period. I got a far better art education through my local community college by far, from instructors who weren’t incrediblely stuck up and full of themselves.

That was an 80k expense that I’m still paying off almost 20 years later, and I didn’t even finish my degree.

I went back to get my AS at a CC and took some art classes there. 10/10, far better instruction for a fraction of the price.

Not me personally, but one of my career mentor’s friend’s took down the entirety of Google Ads as an intern for like 10 minutes. Apparently it was a multi-million dollar mistake, but they fixed the issue so it couldn’t happen again and all was well afterward.
