Not in a bad, "I take the fun out of competition sore loser" kind of way but in the, "anything can be turned into a game." kind of way.
As a person who enjoys playing games this helps my life in all aspects.
Right now Tom and I have an app on our phones called Chorma. Basically you input all of your chores into it, schedule them, and also give them a points value.
It's a game to see who can win at housekeeping. So far I'm slaughtering Tom. I will give him credit where deserved because he does what he can when he can. I have most of the day to accomplish these tasks.
This app makes doing these boring tasks a bit more fun. My house has also never been cleaner. It's still cluttered a bit here and there but we dust twice a week, vacuum three times a week, etc. These things we hated doing but now that we turned it into a game it's kind of fun.
Competitiveness also spills over into parenting.
I don't compete with other parents because kids grow and learn at different paces. You can't compare kids. One kid may be able to read at 4 years old while another is strong in math. Comparing your kid with another kid isn't fair ad ultimately makes you fel like you've failed your child in some way because they don't know this or that.
I compete with my child though. Parenting is a game.
Example: We make ordinary and sometimes stressful things fun. We race upstairs for bedtime (easy way to keep him from whining about going to bed).
Seeing life in a competitive manner helps make it fun for us. We aren't bad sports about it we teach good sportsmanship to Lucas this way as well. He won't always win and that's okay we will try again. He has gotten a ton better at not winning for awhile he was such a poor sport but now he doesn't get too upset he tries again.
I take that as a win.
