Do what you love.
Don't let anyone tell you that doing anything you are passionate about is a waste of time. This world needs more people who are devoted and unashamed to pursue what burns within them, not slowing for the judgement and jealousy (and often misplaced "guidance") of others.
Every step is a moment of learning. The wild-ones harbor no regret, but instead turn towards the future with the dust of our journey displayed proud upon our brow. What a life we have lived, and what more lay before us!
Live your life. Love your life.
Cherish the moments, each and every one of them.
