People with biiiiiig losses/lots to loose

It is so tough at the beginning. I know it was for me anyway looking at it thinking I had over 200lbs to loose. But now I'm over half way I am feeling so thankful that I did make that commitment and kept plugging away at it. What helped me was mini goals, weighing in a unit I wasn't familiar with (I've always used stone, so switched to kg), I don't really know why I felt this helped... but I think the high numbers didn't mean so much emotionally because I didn't know the conversion unless I actively converted it. Also, it's a journey. If one day doesn't work out IT DOES NOT MATTER. This helped me stop that one bad day causing a bad week, which previously could have easily set me back 5-7lbs. So the bigger picture is what matters when you have lots to go. As long as your trend is generally downwards, your doing great, no matter the speed of losses or whatever.
I feel fantastic at the weight I'm at now... I can get up and down off the floor easily, I can put socks and shoes on without struggling, I can chase my 5 year old around, and the stairs at work don't bother me half as much. But I need to stay focused for the second half!
