Hi Want2SmileAgain,
I was on the same boat as you! Back in 2013, I was 80 lbs overweight and my friend called me 'fat' several times... (she too is overweight though not too fat). That gave me the motivation to do some exercise - I started thinking I wouldn't stand anymore 2 months of rigorous exercising, but fortunately, the good gym (Gold's) I joined offered interesting programs - like Pilates, Body Pump, etc and I did that along with compulsory walking each day 6 times a week. AND I was on diet pill (Phentermine) which in my opinion, definitely revved up my metabolism to the point I lost, every single month, 8 lbs each month. Like this, I lasted in the gym for 4 months. Once I hit 34 lbs, I no longer looked terribly obese, and I fell back into lethargy and I stopped... until now..
Recently, my husband who has always been 50 lbs and 2 inches smaller than me, lost close to another 20 lbs. Now he is 70 lbs lighter than me and 2 inches shorter too! When we went on vacation recently, I looked little too enormous for him in all our pictures... My husband has been plainly addressing this and also kinda yelling at me, "What is my problem I cannot even manage to WALK every single day, when I am home and not even working?". I hear him and what he is saying is right. So this is motivational factor #1.
And then my admiration for a very famous movie star (Aishwarya Rai Bacchan). She seemingly gained 40 - 50 lbs few years ago from pregnancy, but she has now lost it all and is slim as ever. Everyday I log into the internet and admire a few recent pics of hers!

She is my motivator, I keep telling myself, well, if weight loss is hard, atleast it is still fair, it has got to be tough for everyone the same way, if she can do it, I can too... Afterall, it would have hurt her as much...

So this is my major motivator factor #2!.
