First of all: remember that you are lucky. I know it's hard to see it that way right now, but you were given an incredible gift in the time that the two of you had together. The fact that it was cut short so abruptly and meaninglessly doesn't take away from that; if anything, it highlights it. In terms of "how", there is no magic answer; you just try to keep learning, and keep giving to others, to the best of your ability. You say that you used to speak for an hour each day; I'd suggest that you spend a portion of that time writing down things you remember-- lessons, anecdotes, etc. The time may come, years from now, when you'll be glad you have some tangible reminders of his advice. Good luck to you.
