Trying to motivate yourself is a pointless endeavor. 
You want what you want whether or not you think you can have it, and you don’t want what you don’t want whether or not you think you should want it. Trying to “get motivated” is a side-issue that only diverts our attention from the main question.

Feelings are a fundamental and unavoidable part of why humans do what they do.  We can’t ignore our emotions.  Because of the way our brains are structured, when thoughts and feelings compete, feelings almost always win.  Research shows that fighting our feelings just makes them stronger.

Motivation comes from inside us.  Either we want to do something or we don’t.  If we want to do it, we are already motivated.  If we don’t want to do it, then why would we?

 

We are often told to make a list of our Goals. 
But most of the things that wind up on that list aren’t ACTUALLY Goals at all.

For example, many people would say they have a goal of making money, but really their goal is the feeling of security and comfort that comes from making more money.  So making more money is actually the STRATEGY, not the goal.

Or take a more personal goal, like being in a serious relationship and/or getting married.  Again, this is a STRATEGY.  Their goal might be to feel a deep connection, and have emotional security.  Having a long-term relationship is a STRATEGY to get them closer to those goals.

In the same way, a goal of becoming Thin is also a STRATEGY. Most likely, the actual goal involves feelings about health, appearance, or relationships.

A goal is the Feeling you ultimately want from the thing you’re seeking.  Ask yourself, “How will I feel when this happens?”  The answer to that question is your goal.

A strategy, then, is the path required to get there. 

When you’re clear on the difference between your goals and strategies, you’ll be more in touch with the big-picture purpose of what you’re actually striving for.  Many people keep pushing toward goals that they’ve set for themselves, and then don’t understand why achieving them doesn’t make them satisfied or happy. Redefining your goals according to how you want to FEEL is a good solution for this problem.

Go to your list of goals, and consider each goal according to this definition.
Rewrite your goal so that it evokes a ...

Completed:
having all parts or elements; lacking nothing; whole; entire; full; finished; no further work needs to be done.

Give this possibility a chance. It is possible to function well, energetically, beautifully, without feeling inferior. It is an Insult to Life to continually feel that you are inferior, less-than, unworthy, or worthless.

Never forget that whenever you are told that you must “Grow” or “Achieve” or “Accomplish” or “Acquire” to become superior, you are receiving a lesson that you need to improve, to be of better quality.  What you are actually being told is, “You are less than”.   Because, what does an instruction to become superior imply? It implies that you are inferior.

You have great regard for people who tell you, “Grow! Rise! Climb! Go! Progress! Gain superiority!”

You never ask them: “Why you are insulting me so?”
You never ask them,
“Am I so inferior that you must constantly tell me to grow and progress?
Am I so ugly that you are constantly telling me to make myself up and appear beautiful?
Isn’t telling me that I need to wear make-up an insult?”

That’s how the intelligent mind functions. It looks at the obvious fact. If somebody near you constantly tells you to go and brush your teeth, what does this obviously mean? It means they think that your breath stinks.

The world is constantly telling you, “Go wash your face, you are not all right”. And you take that as a compliment. “Oh, these are my well-wishers, they are telling me to wash my face”.
 
You never ask: “What’s so wrong with my face?”

And the more someone humiliates you the more regard you have for that person.

Someone will come to you and say, “You can rise up to the stars!” Don’t you see that this statement means that right now you are in the gutter?

But you will say, “This one, this expert, this guru, he is my well-wisher!”

You don’t ask, “Why do I need to rise up to the stars? What’s so wrong with me where I am?”

They say, “You can attain this and that!”
But you never ask, “And why do I need to attain?”

So ….you wear size ze...
