wherewithal: resources (e.g. money, energy, time), means or supplies for the purpose or need
Hi buddies! I don't have the wherewithal to post the rest of this week. So I'm going to drop off another song and an invitation to send me your address if you'd like me to send you a holiday postcard or Christmas card. My email is tabathayeatts(at)gmail(dot)com. Happy Thanksgiving!
