John F. Kennedy on change

Ask not what your country can do for you⁠—ask what you can do for your country.

Leadership and learning are indispensable to each other.

For in the final analysis, our most basic common link, is that we all inhabit this small planet, we all breathe the same air, we all cherish our children’s futures, and we are all mortal.

Change is inevitable. Change is constant.

Benjamin Disraeli1804–1881

Consider how hard it is to change yourself and you’ll understand what little chance you have in trying to change others.

When you’re through changing, you’re through.

Bruce Fairchild Barton1886–1967
