"We cannot get what we've never had, unless we're willing to do what we've never done." -Brian Tracy
Sometimes you have to take a different path to get what you want the most. Maybe you've tried diet X or workout Z, and it didn't work.
Maybe you are at the point that you are fed up and want to give up because "nothing" has worked. But have you tried everything?
My guess is that you have not tried everything and you are just spinning your wheels jumping from one thing to the next because you aren't seeing "immediate" results. The thing about following a nutrition plan or an exercise program is that it takes time. It's a plan that you have to follow for the long term. It's not a quick fix because there are no quick fixes.
This is your life, this is your health. Why would you want to take a quick approach to your health? Do you plan on only living for a short while longer? If so, then go for it. But I'm thinking that you plan on living for a little while longer, so why not take a sustained approach, one that can and will last you for the rest of your life.
You want to get in shape, you want to look great, you want to be healthy and move better. But in order to get there, you may have to sacrifice, you may have to put in some work, you may have to take a different approach. One that takes a little longer. If you invest in yourself, i promise, in the long run, it'll be worth it.
