What touches our hearts and impresses us deeper is sacrifice and humility, when we see someone accept the higher principle of cooperation, putting aside his/her own achievements.
You can think your self to be great, you can go on thinking your self to be great, till you see all fellow devotees going Back Home Back to Godhead, while you remain in this material world only.
If you do some wonderful service and if you tell people what you did in a boastful way, it nullifies the credit of your service, may not be in the eternal platform, but in your conscious condition you will not be able to reap the benefits of that service.
