Follow through or blow it off

I have noticed a bad habit that I have; I will have moments of self discovery where I will identify things that I want to do differently in my life. Sadly, more often than not I will get distracted and never put these new ideas into action.  I need to find a way to change this. Not only would I benefit from this, but my family would as well. 

How would you handle this? Any list makers? Post it posse?
