There is truth in this, however, life’s purpose isn’t about avoiding disappointment. In most things the most growth comes from mistakes, failures, and pain. Don’t be afraid to intelligently, deliberately experience new things, that is what life is for. “As iron sharpens iron, so one person sharpens another.” “If you’re not failing you’re not trying.”
Users and Takers are a bummer but a part of life.... Lower your expectations and you'll never be disappointed with the negative aspects of human nature. Stay true to your goodness anyway. Good actions manifest into good lives...
But therein lies the problem, you can't expect others to do as you would... this is something my girls deal with. My hubby and I will do anthing for our girls and so they think others will too. They are always there for their friends no matter what. Many times they are let down by others. Hard to know because many people are not themselves when you first meet them so how to know who is real and who is only there for what they can take?
I don't believe this to be true in this day and age. Doing everything with a kind heart just gets taken as weakness. I'll stay true to my heart but forget about being nice to those people that don't deserve it anymore.
