Oddly it does still cross my mind, but more in a ponderous way, what will it be like, will I feel like I have had enough life, what do I want to get done before then...
ILoveRachel, this life an be tough, and we can think about dying, I used to think about it and want it countless times, it was like a mantra throughout my waking life "Can I die yet", but things can change, not the world around us so much, but our understanding of it, the way we address it, the way we interact with and see the world around us, and sometimes 1 or 2 key changes, a single true a valuable friend, a lover, a family member, a promotion, 1 key little piece in your life can be a lifeboat to make it all seem ok, to let you rebuild yourself and face the world anew, able to do the things you have longed for, or at least some of them.
Lament the world as it is if you wish, but never stop looking for a way to fix it, in practical terms, and in yourself. Often the way to correct real world problems is to change some small part of ourselves or realise a truth and make ourselves interact with the world in a new and more effective way, to make things how we want them and want them how they are.
