I do not know if this is an INFJ characteristics but I am bad at the most practical things, I can indeed be very abstract, love challenging courses and theories but when it comes to the most simplest things I find myself completley lost, this includes tasks such as simple math logic, Opening a soda can, building a tent etc, I find myself at times unable to do this simple things, and then I end up going nuts about it!! I am constantly breaking things, dropping items, spraying soda gas all over the table!!lol..I don't know what to think anymore..perhaps it is just me..
