There is no formula or step-by-step process in the entire universe that will force a change in your life. YOU have to want to make that change bad enough for yourself. If you do, you'll make it happen. If you don't, you won't. It's a simple as that. It's the brutal truth.
If fitness, you'll fail sometimes. But, you need to make sure you breed success from your failures. And it's a lot easier to believe you can succeed when you know that the other busy people in the world are crushing their goals, rather than idolizing and reaching for the results of some fitness model on instagram that lives a completely different life.
