While it's true there are 'Mozarts' to be found in all fields of creative work, the concept of "artist as inspired madman" is a romantic notion from the nineteenth century. Writing is a craft that can be learned by any reasonably intelligent person, just as anybody can learn to play an instrument if they learn the rudiments and then 'play' with them. When my daughter first started to learn the violin her teacher said, "Your instrument is like a new puppy. You must play with it every day so you can get to know it and it can get to know you."
In a writing class I took many years ago, I remember being told that writers must write something every day. It doesn't have to be original or even 'creative'. For example, even just transcribing a few news articles from a newspaper is better than not writing anything at all. What is important is you regularly engage in the act of writing.
As for creative inspiration, Picasso used to begin every day by pressing a few ink blocks. While these could be quite 'artistic' in their own right, he used them as a tool to generate ideas. A similar tactic for a writer could be to skim through a dictionary and randomly select a dozen or so words and then write a paragraph for each. The beauty of working this way is we don't become so attached to what we write that we can't throw out ideas. It can be rationalized by saying 'it's only an exercise created from random words'. 'The trash can is your best friend'. Don't be afraid to throw out things when they're not working.

This site/wiki is aimed at business executives but you may find it as useful as I sometimes do. The following is another:

Googling "creativity techniques" will also return lots of good results.
I'll post a few more thoughts as I think of them.
