Get the jah-flowmug. (JAW-D)A noble creature that is capable of inspiring joy and happiness to all their person of gratitude sure they may often become overly optimistic but this is soon overshadowed by their own self loathing and then quickly washed away by their confidence this person lives everyday hoping to do something different something new something good but nevertheless they're an everyday average person just like you and me except not they try their best to be themselves the most , they will often make sacrifices for others, and often puts them first as well, but do not mistake this is weakness for they are not a fool they in fact happen to be very wise very intelligent as well their courageous charming funny, they often have to procrastinate before they get things done but they will get it done..... eventually, they also have to be a jack of all trades part of being a procrastinator is being or attempting to be good at things like guitar bass piano video games hacking socializing or even staying relevant.
