Giving is receiving. Like many others, I appreciate how important it is to be given a chance, a break, a hand.
I have always done some work for free and I will keep donating time and expertise directly, by joining others in their efforts or by publicly inviting others to join me in mine.
I am open to discussion about working pro bono. If my heart is not in it (or I simply cannot afford the time), I will be honest with you and respectfully decline. If I know someone who can do a good/better job, I will be happy to try to get you in touch.
