Weaknesses, in insults, in hardships, in persecutions, in difficulties

What does Paul mean when he wrote in 2 Corinthians 12:10 "That is why, for Christ's sake, I delight in weaknesses, in insults, in hardships, in persecutions, in difficulties. For when I am weak, then I am strong." ? Weaknesses: (From Strong's Greek #769) of strength, weakness, infirmity, of the body, its native weakness and frailty, feebleness of health or sickness, of the soul , want of strength and capacity requisite 1b, to understand a thing 1b, to do things great and glorious 1b, to restrain corrupt desires 1b, to bear trials and troubles Insults: (From Strong's Greek #5196) insolence impudence, pride, haughtiness, a wrong springing from insolence, an injury, affront, insult, mental injury and wantonness of its infliction being prominent, injury inflicted by the violence of a tempest Hardships: (From Strong's Greek #318) necessity, imposed either by the circumstances, or by law of duty regarding to one's advantage, custom, argument, calamity, distress, straits Persecutions: (From Strong's Greek #1375) persecution Difficulties: (From Strong's Greek #4730) narrowness of place, a narrow place, metaph. dire calamity, extreme affliction. If you look at verse 9 leading up to verse 10..... God told Paul "My grace is sufficient for you, for my power is made perfect in weakness." Therefore I will boast all the more gladly about my weaknesses, so that Christ's power may rest on me." Did God's grace made Paul strong?
