is it worth it?

days 11 and 12.  I am nearing the halfway mark and i'm wondering is this work and time really worth it? i leave for work at 630 am, after yoga i get home at 730 pm. remind me why am i doing this? i made a vow to myself. i promised i would do the 30 day challenge. i am . but not truly seeing results physically. today, was a small class, the instructor corrected me and others repeatedly. what the hell have i been doing for the past 12 days?   bikram really is about releasing the yoga, and practicing meditation but weight ? no.
