A dear friend of mine recently wrote a post about focus which I find very inspiring and relevant for today’s busy world. It can be applied to music practice, ministry work, relationships, and life in general. http://waterlilywriter.wordpress.com/2012/01/23/the-search/#comment-24
It is good to participate in those activities which help self and humanity and give glory to God. Everything else is not worthy of our attention. Yet, we even need to choose between things which are good. The world is so vast and exciting and we cannot, nor should not, do everything. What we can do is our best moment by moment, trusting and seeking God in those things which he leads us to do.
