I like my life much better when I go up at 07-08:00 and not 12-14:00 but I have this really bad tendency to push later and later everyday until I stay up 24hours , go to bed at 18:00 sleep to 04:00 then start it all over again. But it has to do with being free, I will soon have more habits, training etc which will force me to keep a more normal schedule.
