Hey, I can totally relate--I was hoping to reach my next mini-goal by the time I go back to school (I leave Friday morning) and it's looking like I won't reach that, either. But I'm totally not stressed out about it, and you shouldn't be either! I know, easier said than done, but as Faerie said, mini-goals are something you use to encourage
yourself, not make yourself held accountable and feel bad if you don't reach it "on time." It's something for you to say Awright, I kick a**!
when you reach it, NOT something for to say Booo, I suck!
if you don't. That's why I don't really set specific times to reach my mini-goals... I reached my first one in less than a month, but I've been working on the second one for over 6 weeks and still haven't reached it--so?! The point is that you DO reach it eventually, and you will (very soon)!
Have fun on vacation! It's good to have a reward for all your hard work!
