What are some bad habits that you've picked up over the years that you regret as of now?

Lately I've been going to bed between 3 and 6 am even if I have class the next day.

Eating fast food ENTIRELY too often.

!!! I need to change my sleep schedule but I never do

Biting/Picking at my fingernails

This...

ATRL. I post here instead of doing my homework,

Procrastinating on schoolwork.

This.

Oh and using CraigsList to hook up with dudes

Given out the cookies to easily.

My sleep schedule is the PITS, in every sense of the word.

Also, I chew on the inside and outside of my lips. I have to stop because that is not where it's at.

My sleeping schedule is just awful. I either stay up until 1-2am and wake up at 6am, or I doze off at like 10pm, wake up at 4am, forget to set my alarm, and then wake up late for school

Also my procrastination is a killer. I mean it's 30 minutes past midnight right now and I'm doing homework and then I'm back to my sleeping problem...

I chewed my nails years ago but I'm glad I stopped. It looks so gross.

Posting here right now when I should've gone to bed 2 hour ago. I still have a project that I procrastinated on and have to start in the morning too.

Biting the sides of my fingers like around the nail and cracking my knuckles

Both of these.
