This is an individual sport. Don't worry about how much other people are losing or at what rate. Stick to your plan as much as you can and forgive yourself if you make an error. If you do make an error, go right back on your plan.
You may need to track or tracking may make things harder
You may want to weigh yourself daily or you may find it frustrating
You may hate working out or find out you actually love something you have never tried before
People will probably treat you differently and some of your relationships may change
You may want to keep your surgery a secret or you may want to start a blog about it
You did this for yourself, and you're in charge. Reading about other people's experiences is helpful, but ultimately your experience will be your own. Enjoy the fun things along the journey like fitting into smaller sizes. There really is no final goal, this is a lifelong journey with ups and downs.
