I like the feeling of this poem, and how well it reflects the speaker's mind and soul. And, there are so many connotations which are to be taken from this, so many meanings. Why do shooting stars have to slip by? Why do we not have more chances? Why is it that not all things can be within our reach?
To some extent, they do completely pass, since they are never to return to the same original spot where we once saw them, but their fragments may be found (at least in life as opportunities) later on.
Wave being tossed.....another connotation. Waves do not have much choice but to be influenced by the gravitational force, the currents can be strongly tossed, or they can be gently tossed. Very similar to how things affects all of us.
To me, this poem tells of a story of someone with not enough power to hold things in place and within reach.
