OK,lets philosophy a bit this is not depressing !
I mean we would to defen depression here,but let me continue
For me,this is diving into the unknown ! Going your own way,making your own dreams come true, that unknown being maybe you questioning everything,so you make people around you uncofortable, so you,your self can be more sure what you want, or be it "diving" into the unknown with a new job,project,investing,learning new things,leting go of the old etc. . .
