I think some of the advice here is quite good, but especially given the title of your question, someone has to point out that there's literally a book on the subject called "How to Stop Worrying and Start Living," by Dale Carnegie.

It's a good book. It probably won't solve all your problems without you needing to do some inner work, and I generally recommend meditation as a way to find peace, but also you should read the book since it directly answers your question :)

Yes! I was about to say that this is the actual title of a very popular Dale Carnegie book, and having also read "How to Win Friends and Influence People" (a true classic), I think the advice is timeless!

It comes down to not worrying about things that are not in your control, focusing on the aspects of life that provide real meaning and enjoyment, and surrounding yourself with people who make you your best self. Among other things.

Yes, it's a book nearing on 80 years old but the advice is solid and timeless, even in these frenetic days.

I've also read this book and would recommend it highly, along with How to Win Friends. I read the latter as a kid, and I don't think it has a lower bound on the age it's helpful at.
