Give them variety of experiences in lots of ways. PPs have covered it well.
When DS went to secondary, one of his teachers was thrilled to find out that he was into Warhammer and running and said that so many of the boys have no interests beyond gaming.
I'm not anti-gaming, but any one thing in extremis is not great. They're allowed to watch youtube on the main TV which a) means I get the feel of their algorithms and b) means that I've learned what they're interested in. I've learned to play Minecraft with them and they've appreciated teaching me and me being interested in their world which has been really positive for our relaionship.
My two have the complications of issues like dyslexia (and more) and it's a reason why things can be harder or take more time to master, but it's not an excuse not to try. That knowledge helps support their self esteem. They're not stupid or failing, their brains just do it differently.
Praise effort rather than focusing too hard on outcomes.
Give them space to learn how to fail safely before the bigger stakes happen in the later part of childhood. Learning from errors is powerful.
Talk to each other. I'm a big fan of dinner time at the table. Car journeys are good for side by side conversations.
As a teacher, the hardest pupils to teach are the ones with no curiosity, ideas and too afraid of failing to try.
It doesn't have to come from big, expensive, "Educational" experience.
