I want to be fertile soil

I have recently been struggling with feeling like a failure.  

I have wanted to help people around the world with access to safe drinking water and the Living Water, but I feel like I have very little to show for my efforts or purported intention.

I feel like most of my life is entangled in the cares of this world, being busy like running on a treadmill, much like the third soil type in Jesus's parable of the sower and the soils, wasting time, energy, and resources on things that don't produce eternal fruit.  I want to be fertile soil - 30, 60, or 100 fold - but I don't feel like I know how to break into that domain.

Father, please help me.  Set me free from worrying about the things of this world.  Jesus, I want to follow your model of walking in the Spirit.  Holy Spirit, please show me the way.  I want to love you.
