I look back on all the music I've made so far and I almost feel content, like I could die now and be happy with what I had done.
That's pretty much the exact opposite feeling I have after having spent the last 5 years dedicated towards my PhD research which is tauntingly unfinished. If I were to die, I might just remain a ghost to haunt this world forever as my soul would not be ready to let go. Ah, how I envy you in that regard. Cherish your state of mind.
