How can someone give, when they do not have much to give?
The answer is this: You always have something to give.
Whether it's the kindness in your words, a little bit of time to help out someone in need, grace and forgiveness, or even simply in the attention and acknowledgement that you lend a soul who would need it. Giving doesn't need to be physically tangible for it to make an impact.
After all, the best things in life usually aren't things.
