You can't compare yourself with someone about whom you know nothing. If they have 100+ pounds to lose, they will have months when they will possibly lose 15 pounds, thus the "only" 10#. If you have 20# to lose, you aren't going to lose 15# in a month. In 3 months, I have lost 12# and am proud of it. I'm 12# lighter than I was Thanksgiving. I'll take that!
