A Musing on Bad Blogging and Jealousy

There are tons of things I think about blogging everyday:

A Musing on Fan Fiction
Airbender
Mumbai: Why Is It Not “Mollywood”?
Am I Right On This?
Reviews
Why, Yes, I Am Doing NaNoWriMo This Year!
A Musing on Setting and How It Hates Me
Present Tense: Is It Worth It?

Yet, somehow, I never get around to posting them. “Are you busy?” you ask. Not particularly, no.
Aside from when it comes to writing, I am lazy. In fact, that’s all I’ve been doing for the last two weeks. I wanted to blog about that today, but something else came up. Something I’m slightly embarrassed to admit.
I am jealous of other writers. Even if they aren’t published yet.
A fellow blogger, who shall remain nameless, has posted snippets of their writing. Not only do they have several completed projects, but they all seems to be . . . pretty good. Great, really. This writer is brilliant because they are able to create believable characters and setting, an enticing plotline, and most importantly, they are concise.
As a writer, my weakness appears to be overuse of internal dialog, as well as superfluous and almost theatrical wording. It is difficult to explain, but I had several people point of to me that I often use too many metaphors (i.e a person in my story may represent some longing, or the mention of a hairbrush may foreshadow danger from a certain person who provided it) and too much description. A reader told me the other day: My material is not as raw as it could be. I am sort of TELLING through internal dialog, rather than showing.
Even this rambling blog highlights my inability to be straightforward and concise, but I will not change it now, as I hope you’ll see what I mean.

At this point, I can see no example as to how being concise is not a good thing. My question to you is: Is jealousy healthy for a writer, or even justifiable in any case? As long as I am not angry with the person, could this strengthen my writing in some way? Lastly, what is your weakness (writing or otherwise) and how do you go about fixing that?

Still waters always run deep!
