High BigDaddy
I hope that when you chose the name BigDaddyGreen you were refering to your big personality. Names are powerful and they not only reflect how we see ourselves now, but also how we will see ourselves in the future and you will have to 'wear' this name even when you have lost weight.
Since I want you to achieve your weight loss goals I am going to see the word 'big' as refering to your big and friendly personality and not your weight.
There is an old saying that goes something like, 'begin with the END in mind'.
How do you want to look when you have lost the weight? What do want to see when you look in the mirror? Can you imagine yourself slimmer? Can you see that 'slim daddy' hidden inside that big body?
Congratulations on taking the first step on your journey by joining this wonderful forum.
Good luck
