6. Climb a Mountain
Everest should at the top of this list but that is out of reach for even some of the most talented climbers. No matter who you are, there’s a mountain for you. It might be Snowdonia in the UK, or perhaps Kilimanjaro. Do something that you have to train for and will make you proud. Push yourself to your limits, it’s a great reminder of what the human body is capable of.
