If you stop learning, you will forget what you already know. Proverbs 19:27

My brethren, count it all joy when you fall into various trials, knowing that the testing of your faith produces patience. But let patience have its perfect work, that you may be perfect and complete, lacking nothing.
James 1:2

If any of you lacks wisdom, let him ask of God, who gives to all liberally and without reproach, and it will be given to him. But let him ask in faith, with no doubting, for he who doubts is like a wave of the sea driven and tossed by the wind. For let not that man suppose that he will receive anything from the Lord; he is a double-minded man, unstable in all his ways.
Let the lowly brother glory in his exaltation, but the rich in his humiliation, because as a flower of the field he will pass away. For no sooner has the sun risen with a burning heat than it withers the grass; its flower falls, and its beautiful appearance perishes. So the rich man also will fade away in his pursuits.

Pride goes before destruction, a haughty spirit before a fall. -Proverbs 16:18
