What should older generation teach to younger generation?

I asked in LinkedIn people to answer to the above question and share their comments and thoughts. I got 32 answers, pretty many.

I decided to choose answer by Kay Wallace as best aswer:

"I believe we need to teach family history with our ancestors trials and tribulations. Honesty, integrity, values and respect have become part of our history instead of part of our future. I try to teach my children the value of self worth through hard work and loyalty. Teach them to give instead of take."

Thanks Kay, it was a good answer!
