I actually think that writing things down makes them real in a way that talking doesn't. ... when I write them down, I capture them and pin them to the page or the screen.
this has been scientifically proven - that writing uses a different part of the brain than just thnking - and talking uses another part. my T says that it is important and helpful to do all three - think about things, write them out, read or talk through them aloud - hear it yourself (i guess that's four! i never was good with numbers!!) but the point is - you do process things differently with each activity - and all are necessary - and help get a better understanding - and give more insights. it has really worked for me.
