Some of us are reared with the encouragement to have big goals in life - to be someone important, to change the world, to be ambitious, etc. This stimulates us to have certain attitudes and perceptions that only "achievements" matter.

God has a different idea of "achievements", not in the way the world understands, but in the way that matters in God's kingdom. At times, it might be unclear to me what he wants me to "achieve", but God knows what he is doing.

"I only do what I can with my hands. Then I have faith that God will do his part. Together we'll make a difference."

~ Mother Teresa
