Change

After listening to that song today, something crossed my mind.
Before telling you what actually crossed my mind, here are a few lines of what I heard and remember :

Tell me, I guess that cupid was in disguise, the day you walked in and changed my life, I think it's amazing, [ don't actually remember the rest and don't know the singer-also too lazy to google it ].

So what changed in your life after someone became part of it ?
After hearing this song, I really looked back at how I was before and what actually changed- it's not just the responsibility thing and the fact you share everything with your partner, but a lot more.
She made me quit smoking, she made me realize that I wasted my time on senseless things, and a lot more.

I'd like to know what changed in your life.
