Design don´t need to be brave, but a good design is always brave. To create new designs the designer need to risk, to be brave and not to worry about fail. A risky design can be submited under pressure, destructive criticism, disdain, missunderstanding, forget or unnotice, but a good designer have to be brave about this, and not fear.
Usually, the most special people are doomed to be misunderstood, and then time gives them the reason. What I mean is that people are not always right, and they don´t always know what a good design mean. That is why we have to be honest with ourselves and believe in our work, and not be afraid of negative criticism. We have to be brave and work in what we believe in.
