At the end of last week, I was talking to a C-level executive who has been in his position about 18 months. I asked how he was liking his relatively new role.

He said he was enjoying it, but that there were many challenges he hadn't anticipated. Then he went on to say, "When I first got the job, I wrote myself a note that said, 'Remember, you asked for this.' Every now and then when things get frustrating, I pull it out and reread it."

When I get back to my office on Wednesday, one of the first things I'm going to do is write myself a little note.
