That’s pretty much how I get my teenager to do a lot of things. I tell/show him the part that I know he’ll get excited about. Then after he’s excited about it tell him what he has to do to make it happen.
We were in a serious car accident 5 years ago thanks to an unlicensed uninsured driver. After medical expenses were covered by our uninsured insurance policy we each got a small settlement. Our oldest child was 12 when we got the settlements. We were told the money had to be put into an account until he was 18. I could have selected an account for him but I knew it’d be a great teaching moment so I told him he could decide what sort of account to put it in.
He wanted to do a savings account because that’s what he already knew about. I told him that our bank didn’t have great interest on savings accounts and explained interest to him. We went to the bank and he asked what kind of accounts they have. He ended up going with a 5 year CD since that had the highest interest rate available. Every year in January he gets his statement and gets excited that he earned $150 or so dollars by doing absolutely nothing.
