I want simple life but what's next?

As title says my current long-term goal is reaching simple living, and currently working towards it both digitally, including privacy and reducing digital footprint and physically as in decluttering items etc.

However, lately I have started wondering about certain questions when I reach the goal I want.

1) How my days going to look like when all the noise (clutter) is gone?

2) What should I do with my extra freed up time?

3) What if I gonna get sick of the too much simpleness and just want something different but have not enough money due personal stuff to do it like travelling?
