About breathing, I am fondly remembering the part in Trojan's long poemnovella, entitled: "The Snake of Indetermination: Keepin the Focus of Attention on Your Breathing as This is the Only Route to Moral Being."
In that work, Trojan made the following claim.
"Failing to breathe properly is the single reason for all other moral failings. Therefore failing to breathe properly is a VERY SERIOUS, IMMORAL ACTION!! Breathing normally is THE ONLY THING YOU ARE HERE TO DO."
Ok, look, Trojan found this out through trial and error. But if you want a unicorn to fly to you and whisper it to you while you are on a beautiful, deserted island, during a warm, breezey night, you will want to live as though it is true. I promise you, this will happen to you after about a week or so. But please, remember what I am telling you here. Stop trying to get your "goals accomplished" until you are noticing that not only have you been staying on top of your breathing (continually evaluating it), but that your breathing has dramatically normalized (full, consistent, regular breaths). Under these more optimal breathing-conditions, your "goals" will turn into "passions" before your very conscious eyes. So from here on, I want you to focus on NOTHNG BEFORE YOUR BREATHING!! NOTHING IS MORE IMPORTANT. You may allow yourself to get distracted, but remind yourself as often as you can that all other things are NOT REALLY YOUR JOB. Your life is just something you do WHILE YOU'RE BREATHING not vice versa. You are here to establish a normal breathing pattern under the pressures of and pleasures of semi-awake consciousness. The breathing you are looking to possess here is unforced, instinctual breathing -- you are already set up to do this automatically, but the rise of human consciousness interferes with it. So now one has to be constantly focusing on it. If you must, do nothing for a day or two until you can get your breathing to go on as regularly and and as copiously as is normal -- try doing small tasks while 1) concentrating on your breathing, 2) breathing normally, and 3) smoothly conducting the transaction. This is not as easy as you might think. If you fail to successfully get a bag of popcorn, for example, while mantaining a normal breathing pattern, then you are not yet ready for your hopefully more complicated life. Stay out of life, until you get these small tasks down, then you can move back into your life slowly. It will probably take a few days if you've been living your life as most of the human population is, ie, under the false presumption there are goals more important that mantaining a normal breathing pattern.
About weed and tobacco:
Weed makes you ugly, destroys your dream world (remember the unicorn?) and keeps you from getting a good night's rest. Tobacco also makes you ugly, and will give you bad luck if you partake in it without first fasting 3 days in a row. (See Manual V)
