What was your biggest weight loss setback? How did you fix i

I think for me, my biggest setback was myself & my attitude.  Ive lost weight several times before only to gain it back because i was just going through the motions.  This time around i kinda got forced into making a decision on whether i would be healthy or not.  My health is suffering & im at a point where i can turn around what is going on in my body.  This time, mentally i have to get it right. I can already tell the difference that my attitude makes in my determination to succeed.  I just wished i hadnt allowed myself to get to the point im at.  But shoulda, coulda, woulda. All that matters now is that each day, im determined to make the best choices i can. :-)
