Actually, it makes a certain amount of sense, if you assume some context.
It appears to be predicated on the belief that "sacrifice" and "opportunity" are two poles of a continuum, where "sacrifice" is allowing oneself to be swept along by circumstances, while "opportunity" is recognizing (and reacting to) the possibilities that circumstances may offer for worthwhile change.
"Negotiation", then, is the act of picking those things in your life that you will just let happen, and those things that you will make an effort to change. The author implies that making these decisions correctly helps you to better experience and control "transition" -- the progression between one physical/mental/social state and the next as you go through life. (Ie, "growth.)
Note that "negotiation" is a better choice here than, say "navigation", since "negotiation" implies that the individual must, in effect, have some conversations with himself -- conscious thought and decision-making (with trade-offs considered) is required. "Navigation" implies that one can simply follow a map or street signs or whatever, and this is clearly not the case.
One could offer further arguments against his choice of words, but presumably those words somehow tie into discussion in the larger context.
There are a number of somewhat more trite sayings (such as "Don't sweat the small stuff") that also address this concept.
