A
Giving generously and receiving gratefully make it easier to live happily with others. Yet, why do we have such difficulty accomplishing these things in our relationships? I think people refuse to be generous with others because they fear being used.
For example, my husband and I have family members who only contact us when they need money. We usually accept their requests, but we rarely receive a “thank you”. Most people would say that my husband and I are being used. But when we give, we shouldn't be giving for the purpose of getting gratitude. Rather, we should be giving because it's a good thing to do.
Everything that we have, from our ability to wake up each morning to the money in our bank account, is a gift from the world. In return, the world asks us to use these gifts to help others, either by giving them our time or our resources. The good news is that when we live our lives being nice to others, our lives run more smoothly.
If you're generous, yes, some people will use you. But if you practise being generous, most of your relationships will improve. And at the same time, we should remember to receive gratefully. I truly believe that you cannot say “thank you” enough.
So often we get lazy about expressing gratitude. Parents can feel unappreciated by their children, and teachers can feel unappreciated by their students. Just because a task is part of someone's job description doesn't mean that you shouldn't thank them for it.
Words of appreciation make others feel good about themselves like nothing else. It's good for us to say “thank you” because we often need to tell ourselves how lucky we are. If you are looking for a way to improve your life, I can give you one: Give generously and receive gratefully.
