Daf Yomi - be a part of it!
Well, if you can't be a part of it, at least be a part of the Siyum Hashas on March 1st. Chances are that there's a location near you (See here and scroll down for a list of cities). I remember the last one 7½ years ago. It was an incredible experience. Here are some nice words about the Siyum Hashas by Rabbi Pinchos Lipshutz.
