Check out fencing. Local fencing club has classes for kids and adults all ages. They also do birthday parties, so that might be something different that would be fun for him and his friends.
Maria Shriver has lots of great parenting advice. One of my favorites is (paraphrased): “Children need what you need: to be seen, to be talked to, to feel safe and loved.”
Keep porn to a minimum. Never at school or work. It's normal to be curious but it's really not a healthy representation of sex. Porn is a business. It's designed to get you off, not to be realistic or educational. That's not the way sex looks or how you're expected to behave. Try O.school instead.
Try to avoid the temptation to reach a conclusion too quickly or cling to it too tightly.” (Paraphrasing James Comey from his book ’A Higher Loyalty,’ which I recommend as a fantastic lesson in leadership - and history, and public service.)
When someone suffers the loss of a loved one, don't shy away. Go to the service. Check in during the months following. Say the name of the person who died when you talk to them. Forward pictures of the loved one if you have any, share stories. There are exceptions to this, so always take your queue from the person who is grieving.
Consider the source. Consider whose company they are in. You may not know much about issue xyz but look and see who endorses them. If people you trust place trust in them.
Tube first 2 or 3 years of your life I would sing to you after bath time as I was getting you in your jammies. Two songs: Oh Shenandoah and Danny Boy. Rubbing your tiny little feet with baby lotion while singing to you is one of the happiest memories of my life.
Sadness means you need love. (From another person, a pet, yourself.) Someone whose presence brings you comfort. May be dead, living, fictional, historical figure, religious (god, saints, Buddha, etc.) Live and in person is best though. Let someone love you how you need to be loved.
Awesome game we did at preschool - play I SPY. Try with objects or emotions, such as "I spy something sad" or "I spy something joyful." To help him learn empathy.
Never make someone feel bad for liking something. Not your kids, your friends or colleagues. Joy is a beautiful thing. Cherish it in yourself and in others.
People want to be heard. Listen to your clients, even when they're upset. Don't make excuses or anything, just let them talk. They mostly just want to be heard. Once they're calm, you can solve the problem.
Imagine a hundred different lives. Try a dozen of them. Fail at most of them. That’s part of what your twenties are for. Challenge yourself. Challenge your assumptions. Change your perspective. Grow.
Porn: I wish I could keep you away from it entirely but at least I will prepare you.
It’s normal to be curious, etc. but like anything else, it can get to be too much and can be very harmful, especially to a very young person. It can disrupt your healthy sexuality, ruin your relationships and even your career (no porn at work!)
Also keep in mind it is a business designed to make money, not to be realistic. That's not the way sex looks. Also the women are NOT enjoying themselves.
So try to avoid it, but at least keep it to a minimum!
Pay attention to what people do and what they say. Try to look past their appearance.
This is especially true for women, who are almost always judged primarily on the way they look.
