There are a few ways I think I could find gratification in what I do with computers. Building something that other people use (they could have complains, that's fine). Probability because of humans liking the feeling of being needed.

Encounter a problem and solve it with computers, even more fun, every time you or anyone hit the same problem, they use your tool and realize how easy it's now, that feels great.

You read code/solution/architectures and you go like "Damn! that's clever" or "Oh! that's so neat and lean" or "That made a lot of sense!". Basically, the hit you get from understanding something clever, that means you just leveled up and you'll remember that you understand it now.

Think about other people, how they would use it or whosoever is going to read it. You make it simple for them to read or an elegant solution to the problem. Being able to formulate something, anything, gives a good feeling.

In some sense, the above things are applicable to any field.
