You'll never change your life until you change something you do daily. The secret of your success is found in your daily routine. Maybe adding a daily habit of more love with your child might make a positive change for both of you.
The secret to change is to focus all of your energy, not on fighting the past, but on building the new. Socrates I LOVE this. Especially because I have too much of a tendency to obsess over things in the past.
