A space with natural light, plenty of room and the right ambiance can really help your writing output. In this space, you could have quotes, poems, art, movie posters or all manner of material plastered everywhere. The point is to make it your space - a space that you like being in, feel creative in and can work in for long stretches. Create the time. Finding time to write can be difficult given how busy all our lives are.
Some writers get up a few hours before work and write then.
Others do it late at night when everyone else has gone to sleep. And then keep at it. In your stories, become proficient at using an enigma or series of enigmas. Think of the last five stories you read and work out what the enigma was in each that kept you hooked. The stronger the enigma, the greater your reading pleasure probably was.
