Here's my advice for graduates.
One of my favorite quotes and poems by an anonymous author is:
"It's not enough to have a dream unless I'm willing to pursue it. It's not enough to know what's right unless I'm strong enough to do it. It's not enough to join the crowd, to be acknowledged and accepted. I must be true to my ideals, even if I'm excluded and rejected. It's not enough to learn the truth unless I also learn to live it. It's not enough to reach for love unless I care enough to give it."
If you are not true to your own ideals and beliefs, as long as those ideals and beliefs are good, you will never be truly content as a human being.
