There are various steps to writing; may it be a poem, a short story, a novel, or an article. Frankly the writers who say they spend an hour or two just to write are out of this world. Do not feel less of a writer because you don't; those writers clearly have something wrong with them. To start set up your desk, get organized and have a blank sheet or screen, whatever you prefer. If you want to write cheesy, common unoriginal thoughts, stick with what you have after a few hours of writing. But you will probably realize your ideas weren't as great as you initially thought and your writing sucks, no offense. You then will go into the 5 stages of writer's grief: anger, frustration, mushy brain, hunger, acceptance...

First Stage:

First comes the anger and the self-pity. You feel like you are angry at the world because nothing you write is sounding right. The anger will course through your veins and it won't be pretty. You will feel like smashing things, maybe your keyboard or pencil. At this stage you will still write but your tone will sound angry. #arrrgggghhh

Second Stage:

Then your brain will feel like mush. You will literally be unable to write anything that doesn't sound cheesy or completely unreal. You will get anxious and ask yourself if it is the beginning of writer's block. Try to rearrange your writing environment, the view, maybe even the set up of the room; the change will do you good.
You will feel like doing crazy things, please act on these dumb sounding urges. Otherwise your brain will remain mush. Maybe getting into a new environment or doing things your brains seems to be commanding you to do will be beneficial.

Third Stage:

Then comes the frustration, you will feel like you are lacking something. You start questioning everything: your talent, your choice in writing... I mean are you really meant to be a writer? Yet you try writing again.

Fourth Stage:

After all this, you will feel hungrier and get on a hunger spiral; eating anything in your path, partly from anxiety and partly from stress. Then after filling your hungry worm hole, try writing again.

Fifth Stage:

When you're ready you'll find it is best to write while your ideas are flowing and your mind is not completely empty. Then after writing make sure you read your story again. It will definitely sound better to you, scout's honor.

Have a victory dance ready to perform. You gotta celebrate for finally having that breakthrough. #I'mmmmready
