Sorry, I have to disagree with the entire premise here.
A wide variety of experiences might lead to well-roundedness, but not to greatness, nor even goodness. By constantly switching from one thing to another you are always reaching above your comfort zone, yes, but doing so by resetting your skill and knowledge level to zero.
Mastery comes from a combination of at least several of the following:
I recently set up a host running Ubuntu 14.04 LTS, ubuntu-zfs, and PostgreSQL 9.3. Using the ZFS snapshot feature I was able to make a snapshot of the file system holding the PostgreSQL database, write the snapshot to a compressed file, transfer it to another Ubuntu 14.04 LTS host running ubuntu-zfs, restore it, and launch PostgreSQL using that data directory with all the data (seemingly) intact.
The database is very low-traffic, so I do not know how effective this strategy would be for a busier database.
I take no responsibility if you attempt this setup and it causes data loss or other issues. Use it at your own risk; this document is meant to explain a potential setup and open discussion about limitations and potential improvements.
