Go Irrelevant

Sometimes  it is okay to go irrelevant and  act/speak nonsensically.   It  refreshes your mind.  This is a kind of rest time for mind while not thinking on anything at  all.   A good exercise  would  be to  maximally  randomize your chain of thoughts by jumping  from one idea to other  that might apparently have no connection  with each other.  But  after  all they  are your ideas they  are related.
