In the opening chapter of his The Doorstep Mile(that once again, is highly recommended) adventurer Alastair Humphreys writes:

I have fewer than 2000 Mondays left to live. I want to make the most of them, not just tick them off.

This gave me pause.
How many Mondays do I have left?, I wondered.
I made some quick calculation, based on my family data.
Both my grandfathers died in their early seventies.
My father died at seventy-six.
On my mother’s side we tend to be more long lived – we usually get in our ’90s if cancer does not get at us earlier.
I am 52, so… how many Mondays?

Less than 1300 is a good estimate.
What am I going to do with them?

Humphreys’ idea, presented in his book, is to try and do something that makes me happy. Even something small.
Something that does not drastically change my life overtime, but that in due time will make me able to enjoy a lot more those 1300 Mondays, and all the other days.

I am working on it.
Now I have a deadline.
