I too, am familiar with Einstein's quote. I try to gauge my life by looking back at where I was a year ago - am I in a better place or worse? In some ways, right now, I am in a better place - just got married, job is going pretty well) some ways worse - more weight, still feeling insecure - so what would Einstein say??
Anyway, I too am hoping for the support. I don't know why people repeat the same things- I know not just overweight people do, lots of people do it in many ways. I try not to be too hard on myself, you know?
Anyway, good luck on your journey! Was that personal trainer any good? Maybe you should check in with him/her again?
