To get into the mood of writing I find the best way is to start writing. To the degree I just make myself clear away the distractions and make the time to sit down and write I make progress. If I wait for some mood then forget any real progress.
I wrote a post about how people cannot know if they can write unless they are writing. Something changes in how thinking takes place when people write. Its the same with reading, playing a musical instrument, and lots of activities.
Only when I am writing can I have the experience of a well turned phrase flowing out of me. Only when I am writing will some funny story come to mind to be transposed and expressed.
If anyone wants to write more, write better, make more money writing, then the only thing they can do that will really make a difference is to just sit down and write.
If you are feeling blocked then just write about that feeling and transcribe your own thoughts as they occur then and there. The block will be gone almost immediately. After all you are writing and when you continue to be writing your own thought flow you will gain understanding of your own process. There really is no block at that point because now you are writing and ideas going on in your brain will naturally be drawn out as you continue writing.
The more you write you will learn to write better and faster. This almost magical solution only requires you to discipline yourself to write, so starting right now write a comment here about writing,
