How to feel consistent while searching for work

If you're on a short contract, stay until the end.  In the meanwhile, plan for the end and move onto the next thing but keep doing well at what you're currently doing.  Maybe it'll get better!  Don't be a slacker.  If you're on a longer contract or in a permanent job, it's harder to leave and give notice.  Be strong, give two weeks and move on.  Don't look back.  Be thankful for what you have, your relationships, and the people you've worked with.
