True beauty must come from within.
The beauty of a person is not just for the physically aspect, that we normally see.
Having a beautiful face is a gift from God.
You must take good care of it.
Having a good values plus a good physical appearance makes you more appealing.

Other people feel insecure about the achievement of their friends, classmate, co-worker or even family.
We must not feel that way..
We must support other than to feel jealous.
Be happy on what they achieved..

Use them as your inspiration..
If you feel insecure to others instead of bashing them KEEP QUIET.
Developed your personal growth to at least lessen your insecurity in life...
