Heartwarming / fun.

• The entirety of "The Gambler," especially "You swore you'd be here 'til we decide that it's our time./Well it's not time, you never quit in all your life." Also qualifies as a Tear Jerker.
• "Carry On" is an uplifting song generally, but its chorus quite literally has words to live by.
  If you're lost and alone
  Or you're sinkin' like a stone,
  Carry on.
  May your past be the sound
  Of your feet upon the ground.
  Carry on.
