Gotta push the little shits a little, or else they will just play video games, no? I have no idea what I'm talking about, I have no kids 
But it's interesting how it appears like a country that has harsh laws against cruel training of kids can't compete with nations like China in gymnastics or whatever, where kids are tortured, beaten with sticks as they do their sit-ups.
It's hard work.
1st. You limit their screen time from their earliest days. As they get older they know not to expect TV, video games, social media , YouTube etc....
2nd. This is hard work because kids are full of energy and curiosity and as they get older they'll have friends who ALL are allowed to watch TV play video games, social media , YouTube etc....
3rd. You have to be involved with them. This means you don't get to relax either. It becomes very tempting to let them have TV and video games, social media , YouTube etc....because of their energy levels, you have a hard time keeping their attention.
4. You watch what they're naturally interested in and then offer a little encouragement. They will have1000's of interests and change their mind every 5 minutes as to what they like. Eventually you will see the thing they really love, whether it's sports, reading & writing, building shit, drawing, arithmetic... whatever. Try not to jump all over every little thing they are interested in. A parents over eagerness to develop their children will crush the child's desire. So just offer a little encouragement until you see what the child truly has a desire to do.
5. Once you see what it is, make a small investment: sign them up for soccer, buy them an easel, take them to the tennis court or basketball court, take them to the chess club- whatever it is just make a small investment and sit back and watch.
6. Once they're sure what they're interested in, an you've made the investment, and it's something THEY like - not you pushing what you like- then you support them, become more involved but never let your passion for their success become the motivation, it always needs to be their passion that motivates them.. Otherwise they'll drop out and resent you for it.
7. And you don't want them to be misfits or outcasts, so you want them to have friends that aren't geeks, but aren't too cool either. Good kids who also have interests and listen well and don't watch TV and play video games, social media , YouTube etc....
It all means you have to be an involved parent but never try to turn the kids life into your life by making them do the shit you always wanted to do. It's a lot of work and a difficult balance between involvement and parenting, vs. Overbearing and helicoptering vs. No involvement at all, no effort at all.
