Never Start Work Without a Signed Contract — Even with Friends

The projects that go sideways fastest are the ones that started with a handshake and goodwill. When expectations live only in people's heads, every misunderstanding becomes personal. A written agreement is not a sign of distrust -- it is a sign of professionalism. Define the scope, timeline, payment terms, and what happens if things change. This is especially important with friends and family: a clear contract protects the relationship by keeping business tensions out of personal space.
