Well it's cyclical for me for companies I work 60-80 hours a week then I live off savings for a while and work on personal projects about 42 hours a week, then I go back to work for the man.

To answer whether it is reflected in my yearly income well it depends where I am working sometimes it's kind of just a salary based set up, sometimes I get per hour pay, I don't think any software engineer ever has gotten a time and a half for over time though.
