The Writer's Weakness

So as is with everything that everyone does, it is hard to do it flawlessly without practice. There will always be a small mistake that appears meaningless in the grand scheme of things, but may be of monumental proportions to the one doing the mistake.

Now, I'm not saying I'm a good writer; hell, I'm lazy and have basically cancelled two stories after their release. However, looking back at my prior works, namely A Noise in the Closet and Show Within a Show, and after having read The Looking Glass and its sequel by TwiDashForever and the successor, ScratchnTavi, I've noticed the biggest flaw in my writing process: Progression.

This, I'm sure, has been a problem I've always had. Each chapter of my stories have a vague goal in mind with a few checkpoints to be had along the way. However, every one of them contains very little filler/content between these checkpoints and goals - the appetizer if you will - and instead just tries to get to the main course as quickly as possible, barely giving you time to even take a sip of your drink.
This analogy is an example of what I could be doing, but fail to do in my stories for some reason or another. As such, I'm placing a request from here onward:

If you see something that I could be doing better - be it in my poor progression or any other form - please, leave a critique, pointer, tip, or any other form of comment to let me know. My hopes is that I can begin to change my life for the better. I'm growing slowly closer to adulthood and I'll be damned if I start it off with anything other than a bang.
