I have learned to not be concerned with bad people

There are so many people out there. There is always evil and good. Some people will want to watch you fail and others will want to help you grow. Happiness is finding the good ones and ignoring the bad ones. There are many innocent and nice people. It's the bad ones that you need to weed out like you would remove weeds in a garden. Sounds harsh? Not really! It is realistic those people do not care about seeing you succeed why should you care about them?

In other words, you need to find those who will want to watch you become successful. It is the ones who care about your success and the happiness you enjoy that you should stick to. The other ones that do not care to keep you happy that you should really cut out of your life. Life is not always about making money it is also about good company and good people. What will happen when you run out of money and are down on your luck? What if there are no good people around to smile when you are down on your luck? That's why the best way to happiness is showing care for the good people. Those evil people do not deserve a room in your heart or your life but sometimes you have to deal with evil people. 

In the case of being unable to find any but evil people then at this point you need to play the part.
