I shared the story "3 questions" of Tolstoy with my friends because these are very fundamental questions. Now is the most important time, who you are with is the most important person, doing him good is the most important thing.
As I first participated the challenge, I found it's more easier to make a gift to people who're far far away. Everything you do for them seems special, send a gift, make a call, write a card...And for people you meet everyday, we are more conditioned to daily routine, it will seem so strange if you write a card, buy a flower, treat a lunch to your coworkers every week. Usually I just made very moderate steps, like I just reminded myself to drink water more often, since my coworkers have seen me doing that, my action did some influence so they are doing that too. So just try to do what I like to see on people around me will change my daily life.
By taking such responsibility, I was able to review how fear and arrogance have conditioned part of my decisions. When I do not like a certain part of the work and would like to have someone else to do it, "well, someone has to have it done, if so, why not me?" In this way I can take things more easily and will then focus on solutions instead of excuses. This helped a lot in my life of serving as a volunteer.
