One clone so that I can be a stay-at-home dad without losing my income. Finally finish grad school and fix up the house. Show my kid the world when they get old enough to appreciate it. Get a second job once they start school - something to get me outside, or working with people face-to-face. That would be amazing.
I think I would just need one. We'd have to work in opposing shifts to get my billion Euro idea out the door in a more reasonable time frame than the one I have currently been working in.
