Heeyyyy :)
Well Hey there :) So in the very short 15 years of my existince on this complicated planet, there are many things which have saved into my mislead mind which I am willing to extract, and give to you.
First: It is indeed okay to make mistakes. For those who do not make mistakes obviosly never tried anything new, and will probably live a short life of boringness. Which is not for you.
Second: Be brave. No great story ever came from someone sitting at home waiting for the world to change them (as much as we all love, very too much the internet) So get out there!
and..
Third: Life in wich each human being ever encounters one time, over billions of years. Will always, go on.
