Just looking at the temperature range on Mars. It's 1.5x the distance from the sun as earth and the surface temp ranges from a balmy 70F to -225F.
Elon specifically has this dream of colonizing mars, but it seems unrealistic. Perhaps in the future there could be an outpost where humans can visit for extended periods of time, but living there forever seems kind of sucky.
GU (to guard) LAG (lager; to keep)...keeping doesn't guard one within motion; resisting to hold onto temptations guards growth of resistance from loss through motion.
If one can only exist "now"; then when will one ever reach the future? What does past; present and future of "now" represents other than ones ignorance of perceivable for suggested?
