Why not? We are all going to die. Before the end, make sure you do some of the things that you really want to. Like my friend, Nick, did on his 50th - trekking up to Everest base camp with his best friends. Or even just trying a 'cronut' - donut/croissant hybrid. And all the rest in between...!
Point is - time feels limitless but it is finite. Attempt to transcend your habitual concerns. I've just started reading a book called 'Wild' by Cheryl Strayed - a true story. She decides to go on a solo hike up the east coast of the US - 1,600km. That's an option. (Take plenty of cronuts.)
What countries have you always wanted to see/visit but haven't got round to yet? Make a list. Then eat it. Followed by a cronut.
