Stability is almost as important a feeling as hope and at least for me directly coincides with my happiness. However stability can be our Achilles heel. Once we are in a position that is secure and earns a sufficient living it makes it hard to leave even if you are miserable. If you are in a situation where you feel like you are stuck I would try and find some hope somewhere. Constantly look for a new job, a new scene, anything new that can keep your life interesting outside of work.
