Rather than idolizing perfection, we must choose to cherish what is real. To truly live is to love deeply, to get messy, to sometimes get hurt, and to stumble and fall. It is worth it. The alternative of living a life barren of these things in the pursuit of perfection would be tragically uninteresting.
The alternative to pain may be worse. When you live with an open heart, you will inevitably get hurt. The alternative of living a life closed off from experience, however, is barren. Ironically, it also still involves suffering. In fearing pain, we already feel the pain from our fear.
