Do you want to lose weight? Why? What drives you? Are you capable of losing the weight? How will you change? How will your life change? Will it be worth it? Are you worth it?
Questions like these will often pop into your head. Confronting them with even a small amount of worry or doubt can often derail your plans and shatter your goals.
You must focus on the mental side of weight loss. You must know what you WANT, WHY you want it, and HOW you will achieve it. Your WANT, WHY, and HOW are the mental foundation that sets you on a path to success.
Build a solid foundation.
