Let's define an "impossible person" as a person who seems unwilling  or unable to cooperate with you in some way that feels important to  you.  From your perspective, cooperating with you makes perfectly  obvious sense.  But this other person seems impervious to your  arguments, inflexible in his or her non-compliant decision.
You  might try communicating with this person in a caring, respectful manner,  clearly explaining what you want, why you want it, even why it is in  that other person's best interest to do it.  Yet, despite your best  efforts this individual appears unchanged, or perhaps even more contrary  to how you desire him or her to be.
Then comes the point when you  realize that making additional effort to influence or to get through to  this person would be pointless.
Life's challenges seem always to  be about learning to accept the limits of our graceful control with  confidence rather than driving ourselves into self-degrading, agonizing  stress and strain in a fruitless, maddening battle against the  inevitable.  You merely make yourself into a pathetic victim and feel  increasingly powerlessness and hopelessly dependent if you press on past  this point.
When you reach this point in a relationship, you must  discipline yourself to make no more effort to influence the  uncooperative person in any way.  Though you might feel tempted to lose  your temper and fight on, concentrate on clarifying what you need from  you instead of concerning yourself with what you wanted from that other  person.
Although this often requires that you pass through some  fear in connection with your giving in to your lack of control, on the  other side of that fear you will surely discover a sacred door of  opportunity opening for you as you realize what you really want and your  power to achieve it.
With this comes the most delightful  experience of a rise in your level of personal power. You just might  find this feeling of increased power so agreeable that you actually feel  grateful to the individual who denied you of the cooperation you  sought, because his or her refusal brought you to this state of great  liberation.
You feel far better about yourself in freedom and  self-sufficiency, and far worse about yourself in pathetic dependency.   The deep joy of greater confidence in oneself immeasurably outweighs the  momentary relief of receiving another's aid.
When you worry about  losing a personal or even a business connection with another person,  your remedy lies in pursuing a deeper connection with yourself.  You  have within you the power to meet your every need, but you lose that  power when you make it someone else's responsibility to support you  against that person's will or beyond that person's ability.
You  forge a deeper connection with yourself by doing the opposite of what  the "impossible person" did.  Specifically, seek to really listen to  yourself, to understand what you really want, and to do all you can to  bring it about for yourself.  You have to stop thinking about that other  person for a while and concentrate instead on what you really want that  neither involves nor depends upon that other individual.  You will  discover that no one can really ever take away from you more than you  can deliver to yourself.
Never waste a thought thinking of any  person or experience as a negative.  Thinking of another person as  unreasonable drains you of power, of motivation, of morale.  Thinking of  any situation as "wrong" serves only to make it wrong for you, and  there is nothing else about it that makes it wrong for you.
If you  feel weakened, annoyed, disturbed or in any way distressed by a thought  about another person, it is not the other person who needs to change,  it is you.  You need to change the way you think by dropping the  negative thought, for it does you no good.  How you think of another  person is how you affect yourself with your thinking.  Choose thoughts  that empower you and train yourself to drop thoughts that dis-empower  you.  This practice of mental discipline is one of the most valuable  things you can do for yourself, and it will benefit you far more than  resenting the person who will not give you your way.
Your thought  of another person is not that other person.  Your thought is your  creation.  Your emotional reaction to that thought is a reaction you  engage.  When you think of another person and feel angry or frustrated,  you give yourself that experience.  If you are not aware of that, you  then blame that other person for the way you think and feel about him.   This makes you a victim of the other person's choices, instead of a  master of your own.
How each person thinks and feels creates a  "psychic" atmosphere around that person, transmitting its influence  everywhere.  In other words, how you feel and think influences the  feelings and thoughts of those around you.  Science has found that even  plants exhibit a change in response to the feeling of the person in  their midst.
Now, with that understanding in mind, notice how you  feel and think about the so-called "impossible person."  See your rage,  fear, blame, criticism, condemnation, even hatred as the psychic  atmosphere you are generating, as your contribution to the current  conditions of the world.  Then, instead of focusing on how that  "impossible person" is, you focus on how you are, and set to work on  improving that.
You make improvement as you pay direct attention  to your thoughts and to your feelings, for in that act you deepen your  connection with yourself and lessen your dependency upon the other  person.
