Goal Setting and Habit Changing

I want to be the best father and husband that I can be.  But when I am constantly fatigued, stressing out about bills, and wading through a sea of toys, clothes, and books, this becomes difficult.  I get cranky, mean, and nasty.  A regular Dadosaurus Rex.  So, in order to become the Dad I know I should be, I have decided to do some goal setting, ditch some old habits, and form some new ones.  I don't want to get overwhelmed, so I have decided that I will have no more than one goal or habit change at a time for each of the following categories:

• Health and Fitness
• Marriage
• Parenting/Unschooling
• Finances 
  
• Home Maintenance and Cleanliness 

The ultimate objective is to live a peaceful, stress-free life, in which I have a good relationship with my wife and children (Maybe this is more of an impossible dream than an objective, but it is still worth working toward) So, all of my goals and habit changes should be getting me closer that point.  So, with that being said, I guess I should start thinking of some goals.
