On writing my personal history

I have been working on my personal history for over a year off and on. I've written about forty pages as of today, and am only up to age 26--and that's leaving out the boring stuff! I will need to totally rewrite it when I'm done because I began by putting it in categories, such as school, friends, work, sports, etc., but find that as I've gone on, I've been going by locations where I've lived and included some of the same things as duplicates (most likely, as I haven't yet taken the time to go back and read through the other stuff). That's okay though, as long as I get all my events and thoughts about those events down, I can always edit it later.
It's been interesting going back and remembering. Things early on often are formative in a person's life later on. My main goal with it is to show my posterity why I was the way I was. I think it's nice to know who one's parents and grandparents really are, and I intend to give that gift to them, and in the process show them what my choices and desires in life materialized, show them what went into my decision-making process for major things I've done in my life, and to hopefully get them to forgive me for any harm I may have caused or caused from their perceptions.
After all, it's only a human life, filled with the same kinds of mistakes, loves, achievements or lack thereof, dreams, adventures, and challenges of any other human being. God never made us perfect, only with His characteristics, and the ability to become perfected through Him.
It is a struggle I work on every day of my life, and filling in the details of how that struggle happened, I think in the long run will be beneficial to my offspring and theirs, and in some way pay a penance for my own struggles in life, and a road map as to how my triumphs occurred when I was blessed enough to have them.
In the end it will be rather lengthy, but fascinating. At least, as a writer, I hope to make it so by the time my final draft is complete, and my final chapter written. I don't know how that last bit will turn out yet, and someone else may have to finish, but by the end, my children will know a whole lot more about me. And I think that's a good thing.
