The best tip ever is to not miss the special opportunity to donate money when it really counts the most. This is when you are yourself in financial troubles. Even a very small donation makes huge impact. Take this hard times with joy only because of this opportunity. Once you are well-off again your donations will count very little as they will become just a mandatory duty. Remember the poor woman who gave a small coin out of the little she had and was commended by Jesus! You will never achieve anything like this when you're a millionare no matter how much you donate. Donating your wealth away will only save you from being publicly scourged. But if you donate from your poor state you will get heavenly reward for sure.
