Obsession Bad or Good

I think that being an obsessive person can be bad or good, but in most cases it is usually bad. I believe that nothing in the life is perfect only god. For that reason if you think you can do something perfect that is impossible however we should try to do the best possible in our life, work and family. Also there are people who are obsessed with other people and it is bad. Of course there are some obsession that are good because doesn't hurt anyone and yourself like be organized etc. I think we have to be careful I think about it
