"When can you start?"
You open your calendar and grimace. Next week? Sure, why not.
Several days into the project, you remember… the kids are home next week. The retainer client wants edits. And you probably shouldn't reschedule that lunch again.
Then there are the financial questions. Was that one project really that profitable? You think it took two months. You're not sure.
Margin helps you to map out your commitments each week, so you can live a (relatively) balanced life.
