Perfimism is an inclination to look for negative factors in everyday life and bring forward or implement ideas to overcome the negative factors to make life better. A perfimist believes, why be satisfied with what you have when you can make it better.
This attitude towards life, lies between optimism and pessimism. Looking at things with a pessimistic way helps in detecting flaws and then in an optimistic way the flaw should be removed. A pessimist would blame things around him and never try to change it, an optimist would be satisfied with things as they are and never try to upgrade. While a perfimist brings about change and makes life better.
