We've all heard of Think and Grow Rich by Napoleon Hill, and to narrow down the message it's about your thoughts. If it's important to discipline your thoughts to grow rich, how much more when it pertains to your weight. Remember, it's our thoughts which creates our habits, and the habits which create the outcome.
Here are some areas I'd suggest we should look at before trying another weight loss program:
1) Develop a positive mindset - It's so true, as a man thinks in his heart so he becomes. If you think your program won't work, then the program won't work. Your behavior corresponds to your subconscious thoughts.
2) Develop the faith to believe - In the bible, the book of Hebrews said "faith is the substance of things hope for, and the evidence of things not seen." It's by your faith or your confident belief that you can and will lose weight, and keep it off which makes it possible.
3) Modify your behaviors - We've all had accumulated habit patterns which caused us to be overweight. Fast food is fast, and convenient. However, it's not healthy. If we are trying to change our health, then adjust how many days you buy fast food. Simple adjustments to habit patters can create major results in the long run.
This is the area I'd focus on in my weight loss goals: the long run. We live in a microwave society, and we need everything done today. However, we are overweight because of daily consistent wrong habits over years. As immature as this sounds, to change that, I would propose to make daily consistent healthy habits, and look at your body adjust itself.
