Granted

Once you live in a lovely big house, it's hard to live in a small one again.

Once you drive a luxury car, it's hard to drive a normal one again.

Once you fly first class, "comfort plus" loses its luster.

None of these changes are real. They're felt. But those feelings are real.

So think hard about upgrading certain parts of your life because you might not like the feeling of going back.

If you upgrade, consider it temporary (because everything is) and try to savor the experience. Consider it a one-time gift.

The key is to not take anything for granted.
