That's a good start then I usually have a little notebook by my side in bed (which looks appealing to me so that it doesn't feel like a duty writing in it but much more like a fun thing to do).

Yes, you can try out different methods, but you shouldn't be disappointed if they don't work after one or two tries. Usually something takes a bit more time to work. Of course you can swap techniques to see which one you like most, but personally I would stick with one technique for at least a few months before giving up on it and trying something totally new
What are you planning to try out?
