One of the reason we get stuck in a bad habit, is because we have a bad impression of our selves.
To avoid this, we must change our identity. We must look at ourselves as already the person we want to be.
If you want to be a body builder, start lifting light weight consistently. By doing that, you are already a “body builder” but only lifting “light weights”.
GREAT THING START FROM SMALL BEGINNINGS … You are already who you want to be, but doing SMALLER THINGS.
Continue on doing this, being the SMALLER VERSION OF THE IDENTITY you want … and soon you will be GREAT!
