What is your belief in your own ability to be strong in the LORD, to live as you intend in Him? Do you see any room for growth or are you quite satisfied with your present relationship with God?
Hyperbole is a figure of speech and is meant to be exaggeration, to make a point by overstating. Paul is using a form of hyperbole when he says,
There is debate about whether Paul is speaking of himself or some other man in Christ but the context does seem to be Paul. He is making the point that he is an apostle, one who has seen Christ in the flesh and was delegated by Christ to a specific work and that he has experienced things which cannot be communicated. But then, just when we might think Paul is someone very special, he turns the corner and speaks of the enabling that the LORD gave Paul to encourage him not to become proud, arrogant or conceited in his special-ness:
Paul recognizes that his experience could quite easily draw him into conceit and acknowledges this warning against the tendency to become proud in himself. He doesn’t embrace the reminder but he does come to accept that in him it is likely the blessing of God to protect him from himself. He acknowledges his desire to not have the reminder but accepts that God is sufficient to strengthen him in this weakness, that he does not have to escape to go through with it in the LORD.
In Jesus, His strength likely is best demonstrated through our weakness and Paul confirms that he has chosen to be content in whatever state he is so the LORD may show His ability through that weakness.
Paul concludes this aside on the nature of strength and weakness but the comparison of himself to those who insist upon being superior to the Apostle:
Sarcasm is another figure of speech that is used to draw the dis-similarity between two which are actually more similar than appearance. Paul is not a fool, is not inferior, is not nothing and that leaves the accusers without argument. Humility in weakness wins one for the LORD.
