Imagination is important. And we all have an imagination, which takes many forms and provides different fruit. If you can't dream it, you can't do it.
4 - It's okay to give a shit. Doing anything without your heart is choosing to take the shortcut to nowhere, doing anything with your heart is taking the hard road to a better place.
3 - Help and be helpable. There is a balance between self-sufficiency and self-sacrifice, that's where you become a blessing to the world. Striking the balance is possible, but takes heart, and endurance. And a whole lot of faith.
2 - Choose to believe in people. Relationships are all sacred. Not just romance, and not just friendship, but the connection between people, no matter how ephemeral or time-tested. Choose to know there is always a story there, and the story is worth the audience.
1 - Love is not a limited resource. Time will determine what you can and cannot achieve, but love will never run out, love will not dry up. Everyone is redeemable, everyone can be someone you care about. People will parch your charity and break your faith, but you will not run out of love for them if you just look for it. Don't carry the weight of those you failed, but don't hesitate to show love to someone else. It's not going to fail you. Use it.
