Some Assistance(tips Maybe?) Regarding Tk, an unpleasent situation Options

I am a bit frustrated over TK(arent we all to some extent? xD) but not because of lack of success but because of lack of success born from intent. I will describe a few situations that happaned to me during the times i practiced TK. The main issue is that it happans randomaly and im a person that likes consistancy. The last time made me even more upset since it got me into a situation where i cut my hand pretty deeply and it was very unpleasent(shattared glass door). Anyway... let me eleborate.

Most of the time when i would practice TK i would get either a slight movement\shaking of the object(if it is round) or a very small movement. All this of course while i am focusing on the exercise. Then comes the problamatic(i guess its a problem, not sure really) situations which frustrate me. A few months after ive been practicing(over the years i practice it from time to time), each time, if i am faced with a situation which is emotionaly extreme(very upset for instance) something telekineticaly extreme would occure as a result. Such as me wanting to reach for a hand bag and throw it at a very annoying friend that wouldnt shut up, and as i am reaching for the bag in anger the bag seems to just fly by itself in the direction of her head. Before i am able to reach it phisicaly with my hands. A more recent situation(since ive started once more a couple of weeks ago to practice TK) would be me wanting to close a glass door that wouldnt close. I pushed it once but it wouldnt close all the way and opened again. The second time as i was getting frustrated with it and reached for the door, before i was able to touch it the glass exploded(!) and cut my hand pretty badly as it was flying in all directions.

Now this is all great and stuff of tv shows and movies which we all want and work for... problem is that you can see the diffrence between the results when i try to do it willingly and when it happans randomaly(usualy if i am very upset). Does anyone have any tips to make the "extreme" results the usual? And maybe prevent them from happaning randomaly, as you can tell the last event wasnt very pleasent and now i have to go and get stitches for an opened cut(one of 5 all along my hand, which was far deeper then the others).
I do want to keep practicing and to improve TK but situations like the ones i presented make me feel "whats the point?" you know. Cause if i am allready capable of it to such a degree and practice doesnt lead anywhere close to it.. maybe there is something else i should be doing. :S (simply since TK is an old and sore subject... )

-All random events happaned when i was surrounded by other people or when i was in a social situation\interaction.

-This could be me being sloppy, per say, but to be honest no matter what degree of understanding and control we all think we have... we cannot be perfect all the time hehe.

(I have been to psipog and read manny topics regarding TK, though it would be lovely if anyone is maybe in the same situation i am)

Help would be apreciated,

It is known among consciousness researchers (many of whom are neuroscientists) that telekinesis and poltergeist activity as well is caused by emotional discharges and possible interaction with the human bioelectromagnetic field. Bioelectricity is supposed to be very slight and subtle but apparently it can get big, flair, and do stuff. Documented reports of telekinesis and poltergeist activity often occur around adolescents that are going through adolescent rage problems.

I'm not far from being a teenager, but I know for myself, my most effective magic occurs out of intense, angry or frustated emotion, not poise or "love" or good intentions or even lust or all that.

So you know that you can spontaneously cause telekinesis when you are in a state of anger or frustration and not when you are concentrating or intentionally trying to move something telekinetically. So learn how to harness emotion to cause a desired effect or cause the effect at will instead of by accident. Mastery and intentional use of emotion is an extemely important and hard talent to master in both magic and mysticism. It will serve you well in more than the practice of telekinesis.
