For a few days I have been carrying a quote around with me: "The effort is enough". I got it from the book "Ego is the enemy" by Ryan Holiday. It's a fantastic sentence that exudes incredible serenity.
This quote means that success should be measured by the effort we put into our goals, rather than merely looking at the outcome. And this basically aligns with my view of goals: focus on the things you have control over, rather than things that are out of your control.
