“Those obsessed with glory attach their well-being to the regard of others. Those who love pleasure tie it to feelings, but the one with true understanding seeks it only in their own actions. Think about the character of the people one wishes to please, the possessions one means to gain, and the tactics one employs to such ends. How quickly time erases such things, and how many will yet be wiped away.” Marcus Aurelius, Meditations.
Seeking fulfilment or satisfaction from things outside of our control comes with the risk of being disappointed. All we have is all we are right now – what we generate from within. Recognise the emotions that arise when we place expectation on external things. Time moves on and things change. If you want to win the race, you have to accept that you cannot control the other racers, but you can always choose to take part regardless of the outcome.
