Personal boundaries.

If you have no personal boundaries, you can't have YOUR OWN life as well as be yourself. At any moment anyone can invade your world and stay there as if he were at home without taking his shoes off. In addition, you won't be able to realize your potential and reach yourself the way you dream. After you will build your personal boundaries, your strength, your own thoughts, your real feelings, your future will come to you and you will see it with your own eye.
