What's interesting is that love and hate share very similar neural circuits, except that love omits the judgement and predictive aspects. It almost seems like you can boil it down to:
Love - Acceptance = Hate.
So, in that context, the quote is saying that you have to do things that excite that love/hate circuit. Whether the hatred parts of the circuit (judgement -> disgust -> conjecture and prediction -> movement / action) get excited depend on the individual, but to have a shot at either, you need to risk having both.
I sort of agree with the idea of the quote - that if you don't put yourself out there enough for people to respond you, it will be very unlikely someone will be capable of loving you. But there's something about the tone I don't like. A presumption. I think you are hitting on it.
