　　Balancing work and school is not an easy task for me.My first semester in college has come and gone and I've had to balance a job in there too.Many times I wanted to cut one loose.Honestly I think I would have dropped out of school for my job because I need the money.For a while I made myself believe that school was disturbing my job and my money.Then not only was I trying to do work and school，I wanted a social life.Many times I found that there were not enough hours in the day but I realized I wasn't managing my time right.Hanging out with friends may have been wonderful but it wasn't putting money in my pocket or knowledge in my brain.Friends would have to wait.I was back on the see-saw(拉锯局面)of balancing work and school.

　　Scheduling and planning became the key to my success.Making deadlines for myself and meeting them were important for my college experience.Planning was going well and I felt ready to try and throw a social life back in there.I tried to make plans with friends which didn't conflict with my deadline.That was actually harder than I thought.So once again my social life had to be put off.My friends were very understanding and encouraged me to do my work.Some friends would joke that I was all work and no play but sometimes that's what has to happen to get work done.

　　As the semester came to an end I can say I learned a lot.Planning is necessary for organization.Writing a to-do list at the beginning of the week and actually completing it make me feel good，and it's an accomplishment to be proud of.Not only have I learned something new on organization，but also I've learned a new tool that I can take everywhere with me and use effectively.
