Do you find yourself comparing yourself to others all the time? Are you being fair on yourself – it’s easy to under value your achievements in comparison with others. If you look you can always find someone who can do something better than you – so why look!
In any field of human endeavor there will be experts who specialize or train to such a degree they are at the very top. But it would be a sad, dysfunctional world if no one else bothered. Many thousands achieved a huge amount by completing the marathon on Sunday – I hope none belittled their achievement by comparing themselves to the race winners.
Telling yourself that anyone could have done it is also self defeating. Are you sure? Does it matter? What matters is – YOU DID IT.
