Working hard after being lazy

I've became lazy in the last 2 months and I think that happened becouse of the boring routine or maybe becouse I didn't arrange my time well
every day in those two months, when I went to bed I decided to not being lazy any more but I was, I was lazy to the extent that I used to sleep between 10 to 12 hours a day.
In this period I didn't practice any sport except 2 or may be 3 times, I didn't study well, I didn't hang out with my friends and I didn't do any thing seriously except sleeping=D
Now I've to take alot of things seriously as my exams coming soon, it is not easy to work hard after being lazy.. it takes more effort than anyone can think

"I've become lazy in the past two months and I think it is because of the boring routine or maybe because I didn't plan my time well. Every night when I went to bed I would make the decision to not be lazy any more. However, I continued to be lazy, to the extent I was sleeping between 10 to 12 hours a day. During this time, I didn't play any sports (I didn't do any exercise) except maybe 2 or 3 times, I didn't study well, I didn't hang out with my friends and I didn't do anything seriously except for sleeping. Now I have to take things seriously as my exams are coming soon. It is not easy to work hard after being so lazy...it takes more effort than you think."
