Late Sitting at Office: Profit or Loss

I could never learn how to do a strict time management for myself. Due to lack of this I never found myself comfortable in completing my assignments in time. As a result of this, I had to sit in office in late hours to finish the jobs.

Now I am trying hard to complete every assignments/tasks in hand within the given time line.
