You have read plenty.....and the how? Just start doing it;
-Be quiet and listen....Then eventually talk -Repeat back what was said to you -Ask questions....don't give advice or opinion at first -Understand....then be understood -Go to them....Don't call them to you (specifically the children) -Stop judging until you understand -Reward changed behavior (I.E....The boy does something bad, but tells you. Skip the punishment and reward the good....build trust) -Give a compliment a day...even to your wife on something she has done.
You know what to do.....Start doing it. There really is no HOW, you just start doing it.
BE a man....get rid of the awkward feeling and do stuff.
Home gym....Wonderful idea if you use it. I have a bowflex and a treadmill. ON my bowflex....Between sets I do quick chores. That way you can watch the kids, keep getting things done, and get a work out in.
Newspaper? What is that?......I have the internet for the news LOL
