"When you feel like giving up, remember why you held on for so long in the first place." ~Unknown
First, believe you are worth it! We were put here on this earth to have joy, to grow and experience love and happiness! You can and should have a better life!
Second, you need to know what you want; a healthy body, a fat bank account, time freedom to spend doing the things you want to do. Then, most importantly, talk to yourself about WHY you want those things! Your intentions are key!
Having a strong reason why will help you accomplish whatever you want out of life. We all have the same 24 hours in a day, but some accomplish and have so much more. It's often their why that sets them apart from mediocrity. Take a REAL inventory of where you now are and where you want to be.
*Your why could be because you want to help yourself, your children or other family members have something they need or desperately want.
*It could be that you are in financial trouble and have creditors threatening to take away your home or possessions.
*It could be that you are plain tired of deciding what to eat, where to live, and what to do with your free time based on what's in your wallet.
*It could be that you want to your body to be healthy again or for the first time in your life.
*It could be that you want to improve yourself enough to attract and impress someone into a romantic relationship with you.
Whatever YOUR reason is...
At some level you need to become uncomfortable with your situation, not ungrateful, just not complacent! And as you live through struggles/challenges that come to everyone, you will stay on the right track if you are constantly reminded of why you are working for something better. A challenge is just a test to see how bad you want something. You can do it! You can have everything you want that is good for you!
Your reason WHY will get you through anything and keep things in perspective when times get tough!
To get started you have to write your goals down as if you have already achieved them. Look at it; remind yourself of it every day! Fantasize about how it will look, smell, sound, feel like to be where and who you want to be already.
Then write down WHY you want what you want, and remind yourself of it everyday. Then get to work! The emotion created by knowing your why will put you into motion.
Only after you have written these things down and made the decision/commitment to become THAT person who has what you want and is who you want to be, then you will have the focus necessary to make it a reality. Once you are committed, you will see the universe combine to help you become that person you dream about.
