This was the phrase going through my head today. An ambitious undertaking is what I want right now. Researchers say that people are happiest when they're fully absorbed in a task that is almost too hard for them. Right now, doing something ambitious is likely so appealing because what I'm really looking for is focus; to be able to just concentrate fully on one thing for large chunks of time, to bring together my scattered energies. I want to focus on something that's fussy and involved, time-consuming and challenging.
This is one of the reasons that I decided to hike the Annapurna Circuit in October. It seemed ambitious since it was more hiking and more altitude gain than I had ever done before, and all I had to do on any given day was just walk - no other responsibilities. While I was happy that the trip was successful, I was actually a little disappointed that it wasn't that difficult (we stopped early-to-mid afternoon every day; hiking all day, every day would have made some difference. As it was, I only gave it a 4 out of 10 on the challenging scale).

Hi. I'm in Nepal.
Thankfully my next week or two is light on the scheduled commitments, and I intend to keep it that way; without focused quiet time, life mostly tends to be about day-to-day routine.
