if you want to write the best songs imaginable..... take advantage of the snow at the moment, drag some recording gear, an amp, and your guitar to the top of a big snowy hill...
set your mics up, plug your guitar in, start recording, and sledge down the hill on the guitar while trying to play the dads army theme tune.
go back to the top and listen to the recording, it should be world class. thats how led zeppelin recorded led zeppelin III
