When it comes to your fitness, are you "bored at a job" or "investing in your career"?
Choosing to cultivate new habits vs. engaging in serial dieting and inconsistent exercise is basically the difference between "investing in a career" and "working a job".
When you work a job, you typically do the bare minimum to get by. You don't necessarily care to devote time and energy to getting good at your craft. You sort of know that this job won't be forever and you don't exactly love it...and you're performance reflects that. It's all about getting a paycheck and getting off work to do what you really love doing and often times the paycheck isn't enough.
Investing in your career tends to be a more of a lifestyle. You pursue educational and training opportunities to better yourself. Even though the work is challenging, you enjoy it and it makes you feel content and accomplished. You want success in this field and you're not opposed spending time and thought on your work outside of "working hours." The money important, but it's not everything. You like the process and you know that the more you invest of yourself, the greater return.
Fitness and fat-loss works the same way. If you treat it like a job and do the bare minimum to get by, you probably won't get great results or stick with it. You'll jump around trying this diet, that form of exercise, this new gadget... But if you invest in the process and take the time to cultivate an approach that enhances your life, you're WAY more likely to stick with it long term, see results and continue to build your approach. You'll create something that works for your unique set of needs and challenges you to be improve.
If you're just looking for a paycheck in the form of weight loss and you're in your 30's, 40's, 50's or 60's, I'm telling you you're gonna have to invest in developing a nutrition and movement practice that creates whole-body health. Treating your fitness like a job at which you can do the bare minimum, might have worked when we were younger and our bodies were naive as to our intents, but it just doesn't work for us grown-ups.
Start thinking about your health practices as something worth investing in vs. something you just do for a period of time to get certain results.
