super powers

If I had a choice in having any super power I wanted I would chose to have the power to transform and mold matter into whatever I desired. This would give me the ability to travel through space without a breathing aporatis because I could form oxygen molecules out of the particals of air infront of me. This would also alow me to live on any planet I desired. Instead of having to build my house out of wood and bricks using my bare hands I would simple change the geography of a mountain into a huge mansion, and whenever I get board of where I am living I simply change the mountain back to the way it was as if I were never there and go travel through out the univers searching for a new piece of real estate.
