Eu não sou do tipo que busca (excessivamente) os holofotes.
Não sou de exaltar as minhas próprias qualidades.
Não sou de me vangloriar de mim próprio.
I am not the kind of people that is always boasting about myself
. About how smart (hardworking, clever, popular, beautiful/handsome or any other traits) I am)
I don´t like to be bragging about myself
(about my character traits, about my fanciful car, my homey house, my 25-wage job, anything.)
I don´t like to be bragging on myself, on my jobs, my education, my neighborhood or anything else. I don't like to praise myself, but I am such a damned clever fellow; it is quite astonishing—I never turn my head to a project but it succeeds, anything - everything - never amiss - I´m so clever.

Note: in the last one the guy uses what we call it "false modesty", what he says is the opposite of what he is doing.
And, Zumstein. Great one, congrats! I had thought of that, but you beat me to it.
