The second acrosstic for the word fly is an obvious one: if you don't love yourself, how can you even love someone else? Love is like resonance: when a guitar string is being played on one guitar, and another guitar is near it, the same string on the second guitar will start to vibrate along. For love it is the same, if there is no love in the source, there can not be love reaching the receiver.
It is basically the idea of competition all over again. You can not compete with me not because I am better, but because I wish you to win also! So perhaps we can build a better future together, rather than trying to get the better of one another.
