Bill Gates on change

Your most unhappy customers are your greatest source of learning.

Success is a lousy teacher. It seduces smart people into thinking they can’t lose.

Today, you always know whether you are on the Internet or on your PC’s hard drive. Tomorrow, you will not care and may not even know.

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
