Coworker crush and giving a book suggestion ??

du

So i like someone at work, im pretty sure they like me too but we cant say anything directly because of work regulations. We dont really talk much other than work stuff so maybe hes not intrested or we both just suck at small talk? Idk. I cant even tell if he likes me or not, theres so many inconsistencys.

◾Anyway this is the book and/or quote, im not sure if the quote is to obvious that i like him or to personal as to how i see the world? I'm debating if i should put the quote too or just give him the book name??◾

"We can not change the past; we can have regrets, remorse, memories. The future is insteaid uncertaty, desire, anxiety, open space, Destiny perhaps. We can live toward it, shape it, because it does not yet exist. Everything is still possible. Time is not an arrow with two equal directions: it is an arrow with different extremities." The order of time. Carlo Rovelli
