Bored: Question?

Just incredibly bored with life, realizing if I'm lucky I have maybe 40 years left. Seems like a long time, but still so much I want to do and explore of life and haven't been able to do as much as I would like to do. 

Anyone else feel like they haven't been able to accomplish as much as they would like to do in life? What is the one thing you wish you could do in your life that if you could do it right now, what would it be?
