I'm playing tombraider instead... haha.. what to do to get motivated to do work... am I getting addicted to exercise ?

Last night I could sleep.. I slept at 3 am... and woke up at 9 am... felt bad for sleeping late..... now I still have a headache...

first 6 hours is not really enough sleep our bodies need on average 8 hours a day. second exercise is very good for you and would recommend anyone to do a little each day when possible. the only way I know to get motivated is just to get up and start doing stuff. good luck
