I'd never really thought about in depth before. Sounds really stupid, but I kind of subconsciously thought I was invincible.
But a few weeks ago I woke up and my very first thought of the day was, 'I'm going to die one day' and it absolutely terrified me.
I thought, 'from now on, I'm really going to start enjoying life'. Yesterday I was eating nik nak's on bed, in just my pants, so it's going well.
