Because all my friends are doing it.

Because it's a mitzvah aseh I think I could handle doing, which is perhaps reason enough absent any reason not to. Because I have friends who find it meaningful for them, and it might be for me but I wouldn't know unless I tried. And (related to the first two) it would give me a reason/motivation to say a bracha on the 6 days a week that I usually don't say any.
