No topic gets talked about more and is understood less well than motivation. Most motivational theorists (including clinical and research psychologists) attempt to separate motivation from learning. That is always a mistake!
Because people like what they are good at. If you get good at something like losing or maintaining a healthy weight and form, you like doing it, and you will stay motivated to do it. So-motivated, the perseveration requires little self-recognized perspiration.
Let's see how this unpacks in behavior. I'm about to use a sports example, only because the things and people I will speak of, are well-known. (In general, while I like sports, I hate sports stories and metaphors because they are usually "cheesy", at best, and downright inappropriate and annoying, at worst.)
I was always a basketball freak. I'm not saying I was particularly good at it, but I loved playing the sport and the conditioning it provided my body (minus the injuries, of course). I watched it, too. Although I grew up in Chicago, I was always a Celtics fan. Bill Russell was a god to me, but I didn't learn that much from him, because I just couldn't do almost any of the the things he did -- or, the way he dis them. Paul Silas, on the other hand, although also possessing capabilities I could only dream about, taught me (via demonstration) how to rebound. I saw how he blocked out; I saw how he tipped the ball away from the taller players so only he could catch it; I saw how he used the baseline to catch the ball away from the other players.
While Bill may have been a much bigger inspiration than Paul, Paul was the one who showed me how to succeed. As the saying goes, 'nothing breeds success like success'.
So what does that have to do with losing weight, getting fit and maintaining both?
Learn the techniques that allow you to:
* Manage what, how much and when you eat. And, how, when, and how long you exercise.
* Learn and practice them, and gradually and you will get small, but ever increasing successes.
* Success will allow you to persevere and eventually you will have a big success from persistently increasing little successes.
* Find these techniques from whoever can give them to you.
* If I or anybody else can inspire you, that may be of some value, but the real issue is if I (or anybody else) can provide you with techniques you can incorporate into your own success.
If you enjoy what you're doing because you're good at it, any "perspiration" will be fun!
That reminds me. For me measurement and recording are key, and I forgot to record a food, yesterday.
I'll take care of that, now.
