work to do on a holiday

on 20th of October I will be traveling in Asia for almost a month.

I want to also take this as an opportunity to do some mental work.

I don`t see a point in this months work – how to get it done – however, because I will not work on a project during this time.
I do this work now but I will stop once I am at the airport. 🙂

Can you recommend another Months work for me that I can do while traveling?

My big challenges are all around money and time management.
But I might also profit from taking a break worrying about these things for a few weeks and going back to the basics?
