The first thing to do about an obstacle is simply to stand up to it and not complain about it or whine under it but forthrightly attack it. Stand up to your obstacles and do something about them. You will find that they haven't half the strength you think they have. Just stand up to it, that's all, and don't give way under it, and it will finally break. You will break it. Something has to break and it won't be you, it will be the obstacle.
