I follow many marriage folks on Twitter, and a few who are not marriage related but are just too good to pass up. One of my more recent finds in the second category is Dan Rockwell/@Leadershipfreak . If you are a leader, or want to be one (which should include every husband), I strongly recommend Dan to you. An example of the wisdom to be found is Five Ways to Get Good at Mistake Making.
Mistakes are inevitable; if you try to do things, you will make mistakes, and not trying is the ultimate mistake. Learn to see mistakes as part of the process of finding better ways to do things. Do not try to hide your mistakes or down play them. Own them, deal with them, and go on. How you deal with mistakes says far more about you than the mistakes ever will.
