In what ways does hard work make you feel fulfilled?

Now, when someone hears hard work and fulfillment, the first connotation that pops into their mind is money and recognition, and I think that’s very logical.

However, there are more aspects that serve the feeling of completion when you are working hard.

Another aspect of my hard work that satisfies me is learning something new during the process; furthermore, when I evolve in my job and as a human being, I can improve and contribute a much more significant outcome next time.
