What we're striving for is not something that can be given (or taken away). It's something that you can only take — it's a form of attitude. It is up to you, and you alone, to adopt and keep it. And while there may be no easy way to form your character into one that can do it, while you should expect that only constant work and effort will hold it up even once you've achieved it, something heartening is in that insight, too: just put your mind to it, become determined to get there, and you have made the first step already. It's a substantial step. If you got there, you've taken that attitude for the first time. And you can make it all the way. Take care.
