They say the definition of insanity....

.....is to 'keep doing the same thing' whilst expecting a different result. If you want your life to become more sane and less stressful, you've got to change some of what you keep on doing. You're not single-handedly creating the situation that you find yourself in, but you're certainly shaping it to some extent. You can't control anyone else's behaviour, but you can at least modify your own. 

That's all you need to do. Alter an attitude. Break a habit pattern. Try a new approach. Experiment with a different plan. Then suddenly, all that seems so exasperatingly impossible will begin to become pleasingly feasible.

Peace comes from within.  Do not seek it without.    (Buddha)
