What Can I Do?

Rather nebulous title. I'm at a training seminar in Chiba, at our mission's Japanese headquarters. The topic is leadership. This is the second session (the first having been last September). It has been very timely, introducing subjects about which I have been thinking these past months. After all these years, what have I accomplished? What direction should I be moving in the coming years? The sessions deal with these subjects, so I'm actually staying awake- not a given, in my case(I tend to operate better on my feet).
We have homework, which I put on powerpoints, which my wife linked to her blog (Blue Forest Soapbox), if you are interested. If you are not, I understand!
What can I do? Lots of stuff. What SHOULD I be doing? That's a harder question. At 51, time looks different than it did at 21. I think I've done okay so far, but I want to finish well. There is only one sure event in my future (yours, too) and that's my meeting with Jesus Christ to answer for the things done in the life God has lent me. I'm aiming to hear Him say "Well done". Not that I'm so wonderful, but I do hope to be faithful.
