There's no short cut to success. There's no magic pill or trick.
If that's what you truly need and want then you're in the wrong place. I invite you to click off out of here and find somewhere else on this immense and expanding universe of the world wide web that's going to blow magic smoke up your rear to convince you there is a magic pill.
If you want to get good, you've got to get going. Get your rear in the chair and get those fingers tip-tapping on your keyboard. You've got to put in the sweat equity of time doing the actual deed of writing.
Your writing might be brilliant. And then it might be pure drivel.
That is besides the point. That is not something to concern yourself with just yet.
Write, dammit! Write!
That's all there is to it. Get writing.
You can worry yourself about putting out good, quality writing later on. First you want to put in the time: hours and days.
Increase your word count. Increase the number of words and ideas you've constructed.
The more your read and absorb the works of great writers the more this is going to influence the words you write and the works you create.
And, where possible, consider studying the craft of writing.
But above all: WRITE!
