+2. But each of us has to decide for ourselves when we're financially ready to pull the trigger. Some people are fine with 70-80% success rate (lowest I've seen), others are looking for 200% (twice as many $ as the 100% threshold), and others somewhere in between - and all are right! Each of us will live with the decision, no one else, no one here or anyone else. If you're not as confident as you'd like to be, maybe you should work until you are, most of us can't undo retirement - it's a one way street. But you'll never be 100% confident, and it's likely you will miss some aspects or people from work, so don't wait for that. And if you wait a few years, or many years, odds are you'll still be retired for a good long time.
