Well I'm not normal. I can't do it that way. I have tried and failed miserably. What I do is write the bare bones of the story until it is complete and there is a solid plot. I call it writing cold. That in part is why I can write so fast (16,000 words in three days recently). But I then have to go back and edit hot. I have to add in elements of description using all the senses. Making sure there are some motifs and subplots which follow through the story. Painting the picture so that the reader can see what I am seeing - or at least a version of it. Some might say add some padding to an initially thin story. The best analogy I came up with was doing some tapestry where you stitch all the outlines and only when you have done that do you go back and fill in the colour.
I am not saying this is the right way to do it. In fact, I don't believe there is a 'right' way to write. Instead I think you have to find what works for you. I found this out by trying the 'normal' way and struggling but if I hadn't tried it I wouldn't have known. You have to try things out before you settle into your own style of writing, I believe. It helps you become a better and stronger writer. Or that's what I believe anyway.
Well the music just had to be Carole King and Tapestry didn't it!
