It's true, there are many biblical principles for success.
One verse that is similar:
1 Blessed is the man that walketh not in the counsel of the ungodly, nor standeth in the way of sinners, nor sitteth in the seat of the scornful.
2 But his delight is in the law of the Lord; and in his law doth he meditate day and night.
3 And he shall be like a tree planted by the rivers of water, that bringeth forth his fruit in his season; his leaf also shall not wither; and whatsoever he doeth shall prosper.
Not just reading the Word but to delight and meditate on His Word. Because in His Word are directions for our lives.
