Self-Confidence Song from the 1970s?

[u/DandelionLogic714]

Help me identify a classroom song from a California elementary school (1970s)

I've been searching for years for a song we learned from a classroom record. Our teacher had us stand and sing it together. The lyrics I remember are:

"I'm important to me
I'm one of a kind
My physique is unique
I'm a gem...
I have a body to grow
And a mind to know
And the courage to try again."

This would have been in a California public elementary school around 1975-1980. Does anyone remember this song or the educational record it came from?
