So... clear mind, open heart. See things clearly first. The I Ching or Book of Changes refers to this as "The Creative" or masculine dynamic or "yang." So, at the beginning, clearly see things as they are. See if what is in front of you is a good place for you to be. See all the possibilities that are presenting themselves to you.
Then... surrender to the experience and allow yourself to feel. This is the open heart part. The Creative surrenders itself to "The Receptive" or feminine dynamic or "yin". Loving, feeling, and engaging in life require losing some objectivity and clarity. Feel and be part of it. Then... after the feelings of the experience have passed, allow yourself to see clearly again so you can understand and learn from the feelings and experience that you had.
The concept of non-attachment is one of the most misunderstood concepts in Buddhism. Being non-attached and seeing clearly is essential to having a rich experience. Being detached from the outcome is also essential. But trying to stay unattached while we are experiencing feelings is an exercise in futility and frustration. You end up not being very clear or experiencing anything fully.
So get clear. Do a meditation retreat. Do a vision quest. Soul search. Find clarity for your life. But then take that clarity and focus with you as you come back out in the world to experience life again. Fall in love. Get involved. Feel. We are here to experience things. That is the only way that we can understand.
