David Livingstone’s one regret

“I often ponder my missionary career and in the consideration of my  many imperfections not a single pang of regret arises in view of my conduct except I did not devote a special portion of time to play with my children.  Generally, I was so exhausted by evening there was no energy for fun left.  My children soon sprang up and left me conscious I had none to play with.”- David Livingstone, Journal
