Good opening paragraph?

Sounds pretty good from my opinion. But for your first sentence, maybe you could try something like “In today’s world, true love is a hard thing to come by.” or “In today’s world, true love is a very rare occurence.” But if you like your first sentence better, by all means, leave it as it is. Also, for the second sentence, you could try something like “but every once in a while, someone will find their true love.” I hope I helped, but if I didn’t I apologize.

I like it but I feel like the first two sentences were too wordy. As if you tried to include too many commas and too many words. Perhaps: In today’s world it is very unlikely that you will find our true love. Life is not by any means a fairytale. Though it is more likely to not find true love than to find, it there are rare times when one does find “True love”.

Also you used the word rare too much. Try using “almost impossible” . When you write Gatsby and Daisy fell in love and were made for each other write: Though love seems to be one of the hardest things to find, Gatsby and Daisy were deeply in love with one another. Although things did not work out as Gatsby had wished, it remains clear and untouched that Gatsby and Daisy were made for each other, and no one else.

just my advice ;)
