I understand the importance of giving when you feel good of doing it. You feel bad when you give not wholeheartedly and it makes me feels a part of me is taken. When some part of you is taken definitely you feel incomplete and being incomplete is really bad. But when you give wholeheartedly noting in the part will be missing and you will feel the joy completely as you give.
When somebody borrowed something to me, I assume that I already give it and expect never to return or I will never let them borrow. It’s my fault if they can give it back because it let them borrowed. Hoping them the return the favor will only gives you bad mood, but recognizing the big help you give can make you proud of what you did.
The old books says that when you give it will return a hundreds folds, just give and you will receive. Be careful of what you give, good and bad things must be consider. You cannot expect good things if you give a bad things.
