I post a lot and posting is hard. Writing is hard.
If you think writing is not hard, try to write. Maybe you can do it easily. Congratulations, you're a writer..or at least someone who can express themselves well in writing!
But do something else now: read something badly written. Do it, come on, it's all over the place.
When you read something well written it will make sense, it will click and flow and swirl around an idea touching it repeatedly until it gets to THE point. There must be A POINT or at lest there must be an epiphany of sorts. Good writing elevates us.
Bad writing is the punishment.

@bitdollar asked in a recent post what can we do if we run out of ideas. It's a sneaky questions. Cause if you can write, the ideas is just a prop, a reason to manifest your words into the page. Day in day out, you find it and develop it and carve at it until it makes sense. IT POPS!
How many post ideas can we have?
As many as we can deliver. As many as we can carve.
And here's a little cool trick; the more you write, the better you get. Writing is a skill. You might suck today and you will suck tomorrow but you will suck a little less. A little less. Until someone will say:
I love your writing!
MINE?! no...
Ideas or at least, good ideas are also a skill. Recognizing, Selecting, Expanding. The more you look for them, the more you'll find. The creativity of it all will be on the lookout. Yeah, sounds like a vague and useless advice but like a koan, it will make sense and reveal its truth to you when you are THERE.
Until then - in the inspired and motivating words of Britney -
WORK, b ** ch!
