EVERY TIME you are about to say, "I can't" you have to stop and re-frame that into, "I choose not to"

For example:

"I can't eat that ice cream" to "I choose not to eat that ice cream today because I want to reach my goal"

"I can't eat broccoli" to "I choose not to eat broccoli because I don't like the taste, instead I will eat carrots"

"I can't workout early in the morning" to "I choose not to wake up early in the morning to workout"

Re-framing "I can't" helps clear your head and make you realize that what you thought was a genuine constraint is actually just a mental block you have created for yourself. You are actually in the driver's seat of your choices and decisions. Time to take back that ownership and control!
