Writing things down, using the pen and paper I always carry with me. Doing so, I don’t try to make literature or to sound smart, I just write things down as they come. Later on I’ll read them back, that’s quick, and decide if they’re worth using or if I strike them out and forget about them.

• It frees the mind (no need to waste brain power to remember stuff)
• It helps brainstorming freely, even by oneself
• It helps remember stuff I would otherwise don’t remember
• It helps mixing ideas I may not even consider mixing together

I would not be able to work as efficiently without the simple but so powerful pen and paper.
