The thing about using coke to help (professional) challenges and performances is that you with coke will have to do often redoses, however this is nothing compared to the huge advantages coke posesses to perform in comparison with amps: with amps - if not right away - you most likely rather soon get overstimulated, start tweaking (with your mouth, maybe biting your cheeck or underlip or start grinding with your teeth, or start making repetetive hyperlike movements with your hands or perhaps you bop your leg up and down like crazy,...), you get hyperactive and lose control over how talkative you want to be making you lose control over what you say and eventually your mind seems clear but it turns out to be impossible to produce really coherent thoughts, well simply put: none of that shit with coke, at least as long as you are able to not overdo it, if so it results in some similar problems however less severe, but as long as you can keep yourself on a steady medium level you should be set for success, coke is powerful stimulant, really, only short acting but more importantly it doesnt show itself that powerful cause there is no tweaking, no nerves, no jitteryness, no paranoia, no repetetive hand movements and more such things, you are able to go into what i call hyperfocus, where you are extremely concentrated very steady for a long time with an excellent memory and a huge drive, the intense euphoria is simply a super nice bonus and im not stating that the following last aspect of coke is my absolute favorite but i would like to say that i might consider it possible... of course im talking about the very powerful and highly unique ego boost coke produces, maybe for me this for some reason hit extra hard but i always experienced this in really an intensely powerful way, i really can feel like almost god at those moments, nothing scares me, i am unstoppable, i will be victorious in extremis, and there is not at any moment any doubt in my mind that it will simply be this way, and in combination with certain qualities i posess - one being that i am fully aware of my strenths and weaknesses - this really helped me bring everything to the ultimate level, however i must ask your attention for the severe danger this also brings about and my guess is that if you are in anyway sensitive to this ego boost - be especially if you are a bit shy and not super confident, hold on to your socks it is the miracle you have been praying for but careful its a highly poisened gift - well so if you in any way are sensitive to this ego boost you will not be able to avoid the severe dangers this brings about; you have no doubts that whatever action you take, it will lead to the uttermost success, so you start losing control over calculating risks making you careless and you are so overly confident that you so easily talk yourself into a positition where you now all of a sudden really need to undertake an action you are not at all capable of or maybe simply not ready for leading in no time to complete and utter failure but way worse than that is that the ppl you work with and who's success depends on your success and vice versa just saw you make a fool out of yourself and more so have now largely lost, if not completely, all their trust and the competitive coworkers will most likely also lost some respect for you, it is really hard to avoid these things, i only know two things that give you a shot at getting out of it successfully - it are the two things that got me to success -and thats first make sure you belong to the top of your group, simply be really very good in what you do and know very well what you are talking about, second is just dumb luck...
I think this gives a nice sketch of how coke can be almost the ultimate key to success if it would not carry such severe risks and dangers...
