2 in 7,000: can I be one of them?

Only made it to the gym twice this week, thanks to an especially fussy kiddo and also me being stupid and getting very little sleep. Therefore today I did an all over workout and I feel pretty good! I was still very tired though and it showed.

-6 minutes warm-up on treadmill
-2sets, 85 lbs, 10 reps, lat pulldowns (oh god an I feeling it btw)
-2sets, 10 reps, one at 70lbs and one at 55, leg extensions
-5 minutes on the rowing machine
-2sets, 10 reps, 85 lbs leg presses.
-stretching, walking to cool down

I got very discouraged yesterday after reading an article that mentioned it's normal for people to lose 10-16 pounds and keep it off, but only 2 in 7,000 lose large amounts of weight and keep it off. Those that do keep it off are very driven and focus on maintaining. After talking with my husband I feel better, though, and maybe I can be one of those 2 someday :3. I'll never know unless I try!
