I feel like a bimbo

I read a few of my friend's blogs . They are all so deep and analytical. Should I write things that are more interesting? Maybe use some bigger words? Oh I feel so shallow. But if I try write only when I have someting deep and meaningful to say, that only big words can describe, I will be afraid of writing anything at all, because I fear that I will never have anything truly meaningful to write, or maybe that I will never find words big enough to describe it.
