We can change. People say we can´t, but we do when the stakes or the pain is high enough. And when we do, life can change. It offers more of itself when we agree to give up our busyness.
There is almost nothing outside you that will help in any kind of lasting way, unless you are waiting for a donor organ. You can´t buy, achieve, or date serenity. Peace of mind is an inside job, unrelated to fame, fortune, or whether your partner loves you.
The lesson here is that there is no fix. There is, however, forgiveness. To forgive yourselves and others constantly is necessary. Not only is everyone screwed up, but everyone screws up.
