If you’re not getting what you want, it’s because you don’t have your head right. Loosen up, stop protecting and defending that part of your ego (you know what it is) that you think makes you better — or stop stomping on that part of yourself that you think makes you “worse.” It’s these behaviors — not the behaviors of others, directly — that hold us back most.
It is not that we have a short time to live, but that we waste a lot of it. Life is long enough, and a sufficiently generous amount has been given to us for the highest achievements if it were all well invested. But when it is wasted in heedless luxury and spent on no good activity, we are forced at last by death’s final constraint to realize that it has passed away before we knew it was passing. So it is: we are not given a short life but we make it short, and we are not ill-supplied but wasteful of it… Life is long if you know how to use it.
