good habits turned bad?

I been thinking that i have changed some og my good habits..(which is i think not a good thing..) I was not even late during the primary and secondary school days.. but now.. especially in this year, i was late.. not only once but a few times.. and also need people to write my attendance for me.. haiz.. not only that.. i was not so glued to the television.. at least i can go off to school without sticking around to see any shows that i want to watch..(maybe because that time all morning session..) there is also one more thing.. i never slept so late.. i slept as early as 11pm.. and not later than that.. Nowadays i slept after 11pm.. i also finish my homework before the next school day..(maybe except some of the homework.. i do not know how to do..) Now i did my homework sometimes.. what is wrong with me?? how come my good habits turned to bad habits... why?? *becomes hysterical*
