Can one be too determined?

When someone is determined to do something, it is usually because they have a specific purpose for doing it. Another reason could be it is just something they really want to do. If a person is determined, they can be very persistent in doing whatever it is that needs to be done. Whether it be a homework assignment, getting all the bills paid, finding a job, or just trying to solve a hard puzzle, we have all been determined or persistent at one point or another. However, even though persistence is something to be admired in a person, it does have its limits. If someone works day and night with very little sleep and does nothing else, then their persistence and determination may have gone a bit too far. It's important to be determined and work towards a goal, but it's also important to remember to take a break every once in awhile and focus on other things so it doesn't reach the point of obsession. Obsession is bad for anyone and might cause your work to not be as good if you just took it reasonably.
