There will be times when you will need to put the interests of your tribe ahead of your own—even if their interests conflict with your new lifestyle.

You might need to stay up later than you’d like, or be invited to a party that has food you don’t typically eat. You may go on vacation that interrupts your workout schedule.

Planning ahead will help you stay the course and manage through life’s inevitable curve balls.

Planning can help you stay on your exercise routine even during travel. So will accepting ahead of time that having a piece of pizza at your brother’s party is okay.

Just set up your ground rules and share them with your tribe. You’ll all feel better and less resentful as a result.

And don’t sweat it if your plan doesn’t work out. A big part of lifestyle change is learning to adapt to situations, and trying a different approach when thing’s don’t go as expected.
