Comparing yourself with others will leave you vulnerable on three counts: you'll either feel inferior, superior or impressed. All three of these states are dangerous because they all disregard the underlying principle of our true connection with each other - mutual love and regard, based on independently generated self-esteem.
To protect yourself from this vulnerability, make sure that your attention remains turned within, towards the spiritual experience of pure pride. Staying centred in your elevated self-respect will help you remain undisturbed by others around you.
Keep asking yourself, "Who am I?" "How would my spiritual personality respond to this event or person?" this will help to centre you further, and allow you to enjoy the successful efforts of others.
