One thing for sure, when you got no job, full time IM or do whatever you can think off selling etc via online , you tend to sleep less.
beside stress , also like a thing you need to do , sleep less yet irony wake up early doing your iM , trying all means to see what and how
Irony if you got job , you tend wanna sleep more , one thing for sure , perhaps you dislike your job , but no choice as need money for daily needs , stress also got but kinda is you tend wanna sleep more when you never work
