“Making to” does mean roughly what you found in the dictionary. “She's making to run away” is mostly synonymous to “she's about to run away”. The difference is that “about to” indicates that she will run away in the future and doesn't convey how the narrator knows this, whereas “making to” tells us that the narrator sees something that shows that she intends to run away. She may be getting into a running stance, or distancing herself from the narrator. If she's “making to” run away, she might still change her mind, or be prevented from running away. That is, she is preparing to do it, but she might be interrupted either by internal reasons (change of mind) or external reasons (prevented) — in fact here it's a combination of the two (the narrator grabs her arm, and she doesn't really attempt to escape).
sometimes choices make you
It means that sometimes the choices you make influence who you become as a person.
As noted by @Sam I Am, this is not a normal phrase. It is designed to be the reverse of the first half of the sentence (you make choices), and seems to be ironically implying that while you expect to have control of your decisions, sometimes those decisions can effect (control) you.
In this case, it is also implied that these choices are especially important, hard, or have dramatic (possibly unexpected) results. Less obviously, it is likely implied that some portions of these choices are negative in some way (though this may not always be the case).
Example
During your childhood, you become a delinquent, and end up committing a crime that lands you in prison for 10 years. This choice may "make you" into a fundamentally different person than if you had not gone to prison. Perhaps you now feel compelled to work helping criminals give up their lifestyles (because prison had such a negative effect on your life) rather than if you had not gone to prison and become, say, a wealthy banker.
Alternate Phrasing
Is there any other examples or metaphors that could be meant by that phrase?
The closest I would say would be:
"You (We) are the sum (total) of (all) our experiences"
Meaning what you experience in life shapes your personality, outlook on life and general approach to living.
Best Answer
To make a difference in any endeavour or field means, broadly, to have a significant effect.
Until recently the expression was usually encountered as make the difference, typically the difference between a positive outcome and a flat or negative outcome. For instance, we might say that a star sales manager “made the difference” between her company breaking even and turning a very nice profit.
In the last ten or fifteen years or so, however, the expression has been most often used in exhortations to “make a difference” in your community: to give generously not just of your money but of your time and your expertise to make your community a better place for everyone. Companies proclaim that they want to “make a difference” by supporting local charities, or by providing advice to start-up businesses or by training displaced workers in new job skills. And the rising Millenial generation of young people is popularly supposed to have a more earnest desire to “make a difference” than their self- and family-centered parents and grandparents.
