One way is to feel your way through your new desire. That is that your pretend that you are doing it, living it and seeing how the emotion resonates with it. That feeling is what tells you its a good vibration to pursue with action.
“Feel the power and the freshness of your now: You decipher the contrast. You know what you don’t want. You send out your rocket of desire of what you do want, and now you stand in a fresh new place; you want in a fresh way that you have never wanted before. And that’s what life is. In that fresh wanting, you summon another dose of Energy. If you can begin to savor the mere fact that you have desire right now, and you would stop trying so hard to have that desire be fulfilled and manifested in some physical format, then you would have it.”
