How far can you look ahead?

I know of several people who take things very seriously in life, planning out every detail of their future. They are good people, very organized people and have created systems in their lives that counter and cater to all eventualities and have taken steps such as getting Funeral Insurance for themselves. I don't think I have quite reached the stage yet when I can arrange for stuff like that, but I admire those who can. I bet, it's not an easy thing to do, but some people are a lot braver about them than others, me included.
