What’s something that feels amazing the first time you do it?

Some things in life aren't so wonderful the first time around, like beer (my opinion)... even driving can be more stressful than entertaining at first.

But then there are things that are just brilliant on the spot the moment you do them, like the first time you hear a song that speaks to you immediately.

What's something you ever did for the very first time that was just instantaneously amazing?
