Spending the 99.9% on the 99.9%

When you are helping people, you always are risking the chance of helping someone who is going to take advantage of you. People who are going to cheat "the system." No matter what type of safe guard you have in place, people will find a way to get around them.
Now understand something here, it 0.1% of the people cheating, of the people taking advantage. The rest of the 99.9% need help. So what I want you to do is to spend 99.9% of your time on the 99.9%. Don't let that 0.1% waste all your time. Don't let the 0.1% stop you from helping the 99.9%
In the USA we work bout 2000 hours a year. That means you can spend 2 hours a year worrying about that 0.1% of the people. That includes the time you are mad at them, the time that you are worried about setting up your "fail proof" systems, and the time that you spend trying to recover your loses. Not two hours a day, not two hours a week, not two hours a month, two hours a year.
Spend your time focused on those who need help!
