Travel more :) The world is huge, and we are not as big as we like to think.

Catch the Trans-Siberian. Or the Indian-Pacific for that matter. Watch as thousands of kilometers of untouched wilderness roll by.

Visit some really poor countries and see the happiest people you've ever met living without technology.

See the ruins of vast ancient temple complexes, remains of entire civilisations that are now just tourist traps.

The world will go on without us.
