Be proud of your kids

Be proud of your kids and make sure they know it. 

This doesn't mean congratulate them for getting out of bed in the morning or breathing or any of a number of other banal activities.  False self esteem does more harm than good, that's not what you're trying to build.  

What you should do is recognize their talents, skills, and abilities and make sure they know you acknowledge them and are proud of them; and encourage them to bless others with their gifts.
