If you can’t learn anything from your mistakes then that’s all they are: mistakes.
But if you can learn from your mistakes then they become lessons and I mean people pay for lessons so it’s kind of like making mistakes saves you money- the more mistakes you make the
less money you have to spend for other people to teach you!
Unless you make expensive mistakes..
like forgetting to add oil to your car and then having to buy a new engine… at that point you could pay someone $500 to teach you that lesson and you’d still be saving money.
So I guess find out how much each mistake costs before you make it because it could be cheaper hiring a professional to make it for you.
(Speaking from experience. Which is also valuable, it’s kind of like the interest you earn on all the mistakes you bank)
