> After helping hundreds of families, these are the most common and costly mistakes we see when it comes to The 40-70 Rule. Don't make these errors.

When it comes to The 40-70 Rule, families often learn the hard way what they should have done differently. Here are the five most common mistakes.

## 1. Waiting Too Long

Procrastination is the number one enemy. The best time to address The 40-70 Rule was five years ago. The second best time is today.

## 2. Not Getting Professional Advice

DIY research is great for learning, but major decisions need professional guidance. A consultation fee now can save thousands later.

## 3. Not Involving the Whole Family

Decisions about The 40-70 Rule affect everyone. Keep siblings and key family members informed and involved.

## 4. Ignoring Your Own Needs

Caregivers who burn out can't help anyone. Make sure you're taking care of yourself too.

## 5. Not Documenting Decisions

Keep written records of all decisions, conversations, and agreements. Memory fades, but documents don't.

## Share Your Experience

What mistakes did your family make? Share in the comments so others can learn.
