Notice what happens as you forget about what you want from yourself and the world. What happens within you is determined by you. Being joyful where you are, come what may, enables you to infuse positive energy into goals while also accepting no real need for anything to happen in your life right now. If something does, great. If not, laugh anyway. Detachment is helpful here.
Attachment to a particular outcome is a natural consequence of exclusiveness. The moment you choose between something and something else, or discriminate with expectation, misery is inevitable. Setting an intention and letting go is not taught. The more common response is to cling and get anxious something may not happen. This kind of thinking is precisely what pushes the vision energetically away from experience.
Notice expectation arises from a very limited picture of life. If you wish to yield maximum in this world, then hold no expectations. Create a vision and send it to the universe. By all means take steps to nurture the vision. This does not mean you do not have an orientation. If you have expectation and limited idea of how things can happen, you cut off possibilities and create tension in the chest and other muscles.
Expectation holds power over you when your sense of happiness is linked to the future. Focus instead on the blessings in this moment. Be sure to be in a joyful state before jumping in, heart and soul, to create a different situation. Creating a vision is just as important as trusting the universe. What you do in between affects whether and how the vision unfolds.
