When i saw this post, the first thing that came to my mind was Colossians 3:23-24
And whatsoever ye do, do it heartily, as to the Lord, and not unto men; Knowing that of the Lord ye shall receive the reward of the inheritance: for ye serve the Lord Christ.

Whenever you're doing something, no matter how small or unimportant it may seem, and not thinking what you're going to get in return, that's when good deeds happen. People may not have noticed what you've done, people may not compliment you for it but the good has been done. That's when the blessing you didn't ask for is bestowed upon you. That's when the good amplifies and comes back to you. The world would be a better place if everyone had this mindset that you have.
