People who create lasting changes in their lives are not necessarily smart, or know a particular secret which others don’t.
They are resilient. They understand that with all the progress they make, there will be many more setbacks. Maybe 10 times as much.
By starting with this understanding you expect things not to work out. This means you will be ready for when the going gets tough.
And when this happens allow your resilience to kick in, get back up and try again.
