We have explained through the words of the Sfas Emes and the Chozeh zy"a that recognizing the goodness of exile is the ultimate tool to end it. What exactly is this 'goodness'? Let's take a moment to explain if Hashem gave us any hint to this and how to accomplish it practically.
The Gemara tells us that when the Beis HaMikdash was being destroyed and the holy vessles were being cleared out the exilers notices that the Keruvim atop the Aron HaKodesh were in full embrace. They mocked. "This is what the Jews are hiding in their Holiest of places?" The insult was twofold: They could not understand what this image of Divine Intimacy was doing in the Kodesh HaKodoshim at all, and all the more so they couldn't understand how the image of love displayed by the hugging Keruvim could be relavent at a time such as this. The irony was too cutting.
The She'eiris Yisroel of V'lednik (see more here and here) zy"a explained the siginificace of this imagery by putting it in context with another Gemara that obligates a husband to marital intimacy with his wife before he sets out on a journey. It reminds him where home is and it keeps her desire for him alive even when not in his pressence. Romance is needed specifically when partners are taking seperate roads for now.
This is the deeper meaning of why the Keruvim were found embracing Davka when the Beis HaMikdash was being destroyed. Says Hashem, "The relationship is not where it should be. We need some (a lot of) alone time. I still love you. I aways have and always will." Distance will make the heart grow fonder.
We know that Chazal taught that Moschiach is born on Tisha B'Av. He was born, so-to-speak, through the Keruvim's embrace. An embrace that signified the enternal bond of Hashem and His people, even when they are apart. He is born out of Am Yisroel's desire to reconnect. The intimacy at the time of parting ways.
Appreciating the Galus means taking advantage of the distance to build up our Retzonos. Provided with some "alone time", we are given the oppurtunity to create an inner passion to re-establish the relationship even higher than it ever was.

You will also notice that the video posted in the link is a metaphor for this idea.
