It is destructive to let an obstacle consume you, so that it bears its teeth into you, and imbue its venom into you very being. Think of it as a transcendent cherry blossum. It is frivolous to sit and dwell on one blossum, just because it is lacking in areas such as color, shape and size. And to spend all your time trying to amend that blossum, until it is perfected. It is better to leave the blossum be, and go on to another, for perhaps that one is better and more tasteful. But remember that even if that too is found uneasy, there are still more blossums to chose from, and not all will be so horrid.
