"I can"

Behaviour, decisions and emotions are guided by many things.

You can't always control situations.
But what you CAN and MUST control is your responses to them.
And to do that, you must always stay determined.

Your confidence must never be rattled.
Your mental pictures must always be of you succeeding and
achieving your desired outcomes.
You must be able to make the choices that are good for you
in the long-term instead of just what is easiest in the
moment.

Because tomorrow will be here soon.
You must be ready for it.
You must have the right attitude and outlook.
You must be looking in the right direction.
Because sad, scared, depressed, and angry is no way to live.

Mere "positive thinking" is not enough.
"I can do it"will last a little while, maybe.

But in order to achieve things in more than one area of
life (the one you are most comfortable in),
you need to,you must, and you CAN change a large number of your
patterned ways of thinking.
Not just the "I can" pattern.

It's because change involves altering many thought and
belief patterns.
