Perseverance does not always mean sticking to the same thing forever. It means giving full concentration and effort to whatever you are doing right now.
You must continue to gain expertise, but avoid thinking like an expert.
The less you try to impress, the more impressive you are.
The price of success is to bear the criticism of envy.
You must learn from your past mistakes, but not lean on your past successes.
Success always has a price; success, with integrity, is the real bottom line.
