A "change the world" mentality often ironically serves as a catalyst for discontentment or undue guilt. The common failures and frustrations experienced in the mundane day-in and day-out aspects of life tend to leave those—who had hoped for more importance—jaded or callused as the years progress…
…The reality is that there was only one true and lasting world changer; and, He had to be mocked by men, nailed to the cross, subject to the powers of hell and fall under the wrath of God in order to bring about permanent and lasting change in the world. Whenever we are tempted to want to "think more highly of ourselves than we ought to think," we must remember that the way up is the way down, that he who would be greatest must become least and that the way to the crown is the way of the cross. We must seek to become a "will of God doer" rather than a "world changer"—even if that means changing dirty diapers for the glory of God.

Whatever you do, work heartily, as for the Lord and not for men, knowing that from the Lord you will receive the inheritance as your reward. You are serving the Lord Christ.—Colossians 3:23-24
So, whether you eat or drink, or whatever you do, do all to the glory of God. – 1 Corinthians 10:31
Now there are varieties of gifts, but the same Spirit; and there are varieties of service, but the same Lord; and there are varieties of activities, but it is the same God who empowers them all in everyone. - 1 Corinthians 12:4-6
