Here are three stories from different spiritual practices (Christian Gospel, Modern and Hindu) that points us to the possibility to the good we may be doing as we go on our way without even knowing it.
"The kingdom of the father is like a certain woman who was carrying a jar full of meal. While she was walking on the road, still some distance from home, the handle of the jar broke and the meal emptied out behind her on the road. She did not realize it; she had noticed no accident. When she reached her house, she set the jar down and found it empty."
-Gospel Of Thomas
"There is a Sufi story about a man who is so good that the angels ask God to give him the gift of miracles. God wisely tells them to ask him if that is what he would wish. So the angels visit this good man and offer him first the gift of healing by hands, and then the gift of conversion of souls, and lastly the gift of virtue. He refuses them all. They insist that he choose a gift or they will choose one for him, 'Very well,' he replies, 'I ask that I may do a great deal of good without ever knowing it.'
The story ends this way: The angels were perplexed. They took counsel and resolved upon the following plan: Every time the saint's shadow fell behind him it would have the power to cure disease, soothe pain, and comfort sorrow. As he walked, behind him his shadow made the paths green, caused withered plants to bloom, gave clear water to dried-up brooks, fresh color to pale children, and joy to unhappy men and women.
The saint simply went about his daily life diffusing virtue as the stars diffuse light and the flowers scent, without ever being aware of it. The people respecting his humility followed him silently, never speaking to him about his miracles. Soon they even forgot his name and called him 'The Holy Shadow.'

A water bearer in India had two large pots, each hung on each end of a pole which he carried across his neck. One of the pots had a crack in it, and while the other pot was perfect and always delivered a full portion of water at the end of the long walk from the stream to the master's house, the cracked pot arrived only half full.
For a full two years this went on daily, with the bearer delivering only one and a half pots full of water in his master's house. Of course, the perfect pot was proud of its accomplishments, perfect to the end for which it was made. But the poor cracked pot was ashamed of its own imperfection, and miserable that it was able to accomplish only half of what it had been made to do. After two years of what it perceived to be a bitter failure, it spoke to the water bearer one day by the stream. "I am ashamed of myself, and I want to apologize to you. "Why?" asked the bearer. "What are you ashamed of?"
"I have been able, for these past two years, to deliver only half my load because this crack in my side causes water to leak out all the way back to your master's house. Because of my flaws, you have to do all of this work, and you don't get full value from your efforts," the pot said.
The water bearer felt sorry for the old cracked pot, and in his compassion he said, "As we return to the master's house, I want you to notice the beautiful flowers along the path." Indeed, as they went up the hill, the old cracked pot took notice of the sun warming the beautiful wild flowers on the side of the path, and this cheered it somewhat. But at the end of the trail, it still felt bad because it had leaked out half its load, and so again it apologized to the bearer for its failure.
The bearer said to the pot, "Did you notice that there were flowers only on your side of your path, but not on the other pot's side? That's because I have always known about your flaw, and I took advantage of it. I planted flower seeds on your side of the path, and every day while we walk back from the stream, you've watered them. For two years I have been able to pick these beautiful flowers to decorate my master's table. Without you being just the way you are, he would not have this beauty to grace his house."
