Familiarity Breeds Contempt. Absence Makes Your Heart Fonder.
When you have your favourite playlist on repeat, you get sick of awesome songs. It starts feeling a little sucky initially because it's a pity you'd not feel the joy of listening to them anymore. And then this feeling becomes nonchalance and eventually a reality when you find new, and presumedly better songs.
Today, I played back some of these songs and I realised I still treasure them. Maybe not as much when I first heard them, but they are still awesome.
... And I think this echoes in my personal life as well.
