I haven't thought about this, because all I think about right now is to get out of my shell and be "normal". But I would love to:

1- Learn how to ice skiing.
2- Sky diving.
3- See the aurorae.
4- Visit Eiffel tower.
5- Learn guitar.
6- Learn how to swim.
7- Jump from a cliff into water.
8- Try a zip line.
9- Visit Agia Sofia.
