every time I felt too proud of myself...

Here's the trick:

1. Open Google map.
2. Choose the satellite view, or better, 3D.
3. Zoom out until you see the whole world.
4. Untick all the labels, names, and vids.
5. Find yourself.

If you can't, why so proud of ourselves for all the big things we got?

All our achievements, knowledge, richness, ranks, abilities, greatness are nothing. They are only worthy when they benefits others and not just our own selves.

So, did you found yourself?  =)
