53 classes in 58 days..

i've managed to do 53 bikram yoga classes in 58 days (i can't make the friday classes, otherwise i would totally have not missed them, plus the puppy was sick one day) i started doing doubles to make up for them... as i'm nearing 60 days, i'm wondering will i complete 90 classes in 90 days? or 101 classes in 101 days?  i'm not even sure what my goal is... i'm 5 classes off which doesn't seem like much but every friday i miss a class so really if i do one extra class on saturday to make up for it, i'd have to do 5 extra sundays as well to get to a 1:1 ratio, it seems like once you are behind, ur always going to be behind, i don't know if i can do 5 weekends full of doubles... i think i need to set my goal, figure it out, then i have some sort of motivation cuz right now i'm just kind of going along with it... if i have time on the weekend or feel like it, i'll go to an extra class, if not... no biggie.. thats a great mentality but at the same time, i'm feeling like i have no drive

and why does 90 days seem sooo much longer and farther than 60 days?  i feel like i can't make it to 90 days... but i have found this new appreciation for yoga and i don't dread class at all, i appreciate going to class, its never hard for me to get up and go, but nine zero seems like a very large number, there's 30 days between 60 and 90, but the number 90 just seems like it grew exponentially larger from 60
