Hi Tim,
let me add some of my own wisdom to all the good proposals already posted.
Three lessons you could profit from:
A lesson from Project Renaissance: Borrowed Genius
This is an application of ImageStreaming. You take the place of a master in the field you are currently learning, experiencing the world through his senses. The procedure can be found on the web, but it will take you some time (a week or two) with daily practice to use it.
I hesitated to suggest this for two reasons: 1) I have no personal success with Borrowed Genius, 2) You already seem to do a LOT of things simultaneously, one more could be one too much.
A lesson from Marketing: Concentrate your resources
In marketing, if you want to become a major player, it is wise to first concentrate on a particular service, product, kind of customer or area. Doing this, you can gain experience, don't have to many ends to work on and, hopefully, can make profit more early.
So, perhaps you should concentrate on one area of your interests, e.g. Qi Gong, if it does, what is claimed. Succeeding in this one area, you can move on more confidently.
A lesson from Writing: Turn your back
When attempting to write something, it is a good thing to prepare. Sometimes preparation is enough, the words will come, the text will flow. But sometimes... nada. rien. nichts. nothing. What to do in this case? Well, one favourite, time-honored, proven and successful way is to turn your back on the topic, to do something completely else. Go dancing, walking, watch a movie, play a game with some friends, delight yourself in some books or comics. But before you do, have the feeling that you will have your ideas in time, that you will succeed. Then stop second-guessing yourself, forget about the whole thing. And, in due time, your inner mind will pop up the headline, the first senctence, the theme of your writing.
To say it short: Preparation - Incubation - Illumination.
To me it seems you have prepared yourself really well, you stuffed your self with a lot of good things. Perhaps, now it is time to just let go for a while and let your inner mind do its own thing: "Read 'em all, let your subconscious sort 'em out". Turn your back and have some fun, get a new perspective and handle on your life.
OK, school's over. Now run, the sun is shining and the whole world waits for you.
Have fun,
Jens
