Why blogging is so difficult

Lately I have pondered why I find blogging so difficult. I like to read other people's blogs (people I know in particular). I like the idea of blogging in general. So why don't I blog regularly?

I have come to several conclusions:
1) I think my life is interesting, but I don't really think other people would think so. So why inflict my life on others?
2) I cannot write with abandon. If I publish something on the internet, it must be carefully proofed and the implications considered. I would not want someone else to misinterpret what I write. I would not want someone else to abuse what I write. I hate the idea of making spelling and grammar mistakes.
3) I find it very difficult to write down just a little bit at a time. When I write letters (as those few friends who have ever received a letter from me know) they tend to be long and cover the complete history of my life since I last wrote. The longer it takes for me to get around to writing a friend, the longer between letters, which makes it harder to find enough time in my schedule to write a long letter, etc. I just find it very hard to do things half-way!

So why do I like the idea of blogging? It would give me some sort of record of my life. I have a hard enough time of remembering what I did earlier today, let alone last week or last month.

So far the cons outweigh the pros.
