I've decided to take the plunge and do a blog. And I ask myself:
-Will it get me anywhere?
-Will anyone even care to read it?
If it offers me nothing more than an online journal to vent my thoughts and percolate some ideas, does that make it less or more meaningful?
It's like being in a writing contest. You wonder if anyone will read it, like it, or send you hate mail. But what you take away from the experience is the important part.
Life (blogs, writing) is all about what you learn and how you use that knowledge.
