humility

If anyone would like to acquire humility, I can, I think, tell him the first step. The first step is to realize one is proud. And a biggish step, too. At least nothing whatever can be done before it. If you think you are not conceited, it means you are very conceited, indeed.
C.S. Lewis

servanthood...

We are not called to help people. We are called to follow Jesus, in whose service we learn who we are and how we are to help and be helped.
Stanley Hauerwas and William H. Willimon

An invitation to mission work...

If you want hard work, and little appreciation of it; value God's approbation more than you fear man's disapprobation; are prepared, if need be, to seal your testimony with blood, and perhaps oftentimes to take joyfully the spoiling of your goods... you may count on a harvest of souls here, and a crown of glory that fadeth not away, and the Master's 'well done'.
J. Hudson Taylor

get some sleep

Go to bed seasonably, and rise early. Redeem your precious time: pick up the fragments of it, that not one moment of it may be lost. Be much in secret prayer. Converse less with man, and more with God.
George Whitefield
