Lost in thought, and drifting away...

Its the second week of school. I was in the bus going towards SIM. I alighted halfway decided that I am not going to school. I dont know. I am confused now. Should I or should I not go for the lessons that I will be taking next semester? He said I should go if there are lessons for me. I should study because I am still a student. This morning I woke up thinking why should I go for the lessons. I end up wasting my time thinking should I or should I not? And now I am still thinking. Help me please~~ ...try again or walk away...
