You can control your thoughts. Music is the easiest choice -- and the most addictive one. If you feel that your thoughts begin to ramble away from what you need them for, turn on
a non-annoying melody or something that helps you think if you are were in the almost complete silence,
or turn the music off, stand up, and forget what you heard and saw for a minute or two.
Then return from the music realm or from the silence --
into the quiet. And think.
Remember, the music must carry you on towards the goal you seek for, just like a
gentle wave, -- not drag you away like some Benny Benassi butt-swooping sax band who needs yer bling and yer mojo.
Be careful with music with dominating and loud drums, or with lyrics that
you understand: cliche-ed thinking is not too good, and listening to the same order of words for quite a time prepares the ground for this disadvantage.
Remember: laugh defeats serious mood, serious mood defeats laugh. Counter bad silence with good music, and counter
over-used or bad music with good silence. Staying on the same side every time is bad in this case: both sides have
their advantages. Find them and use them.
