Here are two potentially helpful questions in figuring ourselves out:

--are there talents/skills/activities that we rejoice to use or do?
--are there talents/skills/activities that cause us to lose all sense of time when we use/do them?

I found these in "How to Find Your Mission in Life" by Richard N. Bolles.

Some might be put off by this book's overtly religious orientation, but, to me, the two questions above seem potentially pertinent and helpful regardless of whether one is religious or not.
