Wherever you are, be there totally. If you find your here and now intolerable and it makes you unhappy, you have three options: remove yourself from the situation, change it, or accept it totally. If you want to take responsibility for your life, you must choose one of those three options, and you must choose now. Then accept the consequences.
Right intention is like muscle—you develop it over time by exercising it. When you lose it, you just start over again. There’s no need to judge yourself or quit when you fail to live by your intentions.
