I don't wanna study today

Good then don't study.

I always wanted someone to tell me this. :D

Have Fun :)

Sometimes i regret why I enrolled haha.. 

Think that there are others who would like to study but they can't (no money) and think how luky you are. 

we have the same feeling

Don't worry

It can be seen in some diligent students also . As you can not expect every day you are so energetic and happy to work . But rather  , hard working people will find the good cause to brace up to move on and lazy people always excuse to do nothing for their tardiness .
