Blessed are those who listen to me,
watching daily at my doors,
waiting at my doorway.
(Proverbs 8:34)

I'm not good at waiting, especially when it's on your timetable, not mine.  Keeping someone waiting is simply inconsiderate and rude.  However, waiting for the Lord is totally different.  I don't know the exact time that He will arrive, so I won't be inconvenienced, angry, or disappointed.  I will be patient, knowing that He will arrive in His own time, which is the perfect time.
