Work on interesting things or make the things you're working on interesting. Don't work only for yourself; take on the mind of a servant and you'll often be grateful. Don't look for total fulfillment from the things you can see, or the things that pass away. Store up treasures in a place that won't fade away.

It's just a job.

Always leave them wanting more.

(disclaimer: I've been in the industry for over 40 years... these days I avoid burnout by counting the dollars until I retire)

Choose based on what you want to do, not what other people want you to do.
