How can you get yourself interested in your work?

Life is lived Inside - out, not Outside - in.

You don't get a job and love it. You love a job and get it.

Nevertheless, you can still inspire yourself in the field to get an interest in it. Like:

1. Reading about the greats in the field (e.g Alan turing, Don knuth, Linus torvalds, etc.)

2. Reflecting on the beauty of coding and code.

3. Reading and reflecting on the simple idea of computers which is Computable Numbers and the Theory of computation.

4. Get around an environment of really good and passionate programmers, the non-arrogant ones tho'

if these doesn't help, probably leave your work and try to re-live life Inside-Out
