Soldering is life.... Well, not really, but it IS a great life skill.
Once you can solder, there are a whole lot of cool projects you can do that were a closed book before. If you have any friends who play electric guitar you may find your skills in demand (fixing, upgrading, modding pedals, building pedals, etc).
Weller irons are the bees knees, but Hakko are also decent if you don't want to fork out the dough for a Weller.
Getting laid gets way too much focus (in media and social consciuosness), proportionate to how much time it takes.
