1. Lacking belief in one's self shows a lack of self-esteem. Keeping working on your writing skills and perhaps you'll be able to put out something that makes sense.
2. We're back to reading and writing in English. What this sentence says is that you do not belief in this hogwash you're spouting. Now, while I actually believe this to be true - that you don't believe what you're saying (half the time what you're writing doesn't make sense, anyway), you want us to believe that you do not believe in anything, not even yourself. Sad, so sad.
I don't think it's belief you lack. More like writing skills and English comprehension. The motif with all the pix and oversize printing does fall into your low self-esteem bit, you overcompensate for attention.
But, as I posted above, Porpoise won. Therefore, you (and non-beliefism) lose.
But non-beliefism doesn't exist.....because no one, not even you, believes in it! You say so yourself. So, please, stop self-editing your dictionary, actually LOOK UP THE DEFINITION OF BELIEF (hint: it's been posted here) and find someone to explain it to you in small words in whatever your native language is (I'm hoping it's not English).
