I need to stop doing this,
"Fk I have this, this, and this due tomorrow. Well time to implement this cool new thing I found yesterday in my personal project. *2am* okay if I sleep for 4.3 hours and then..."

Why don't I just do required stuff first so I don't have to stress?!

Because we're programmers!

We didn't get into this because it's easy.

We didn't get into this because it's necessarily fun.

We got into this because we like a challenge. Most of us also work very well under pressure. So what do we do when the work isn't pressuring and challenging enough to stimulate us? We create our own artificial pressure by putting off work until the last minute, so we can frantically code everything last minute, get it done just in time and get that boost of adrenaline and confidence from feeling like we can do anything that is thrown our way.
