Pick a few words you want people to use about you. Then act like them on purpose until they’re true.

Reputation is not assigned, it accumulates out of behaviour, which means you can aim it. Choose two or three words you would want said about you and they start working as a filter at the moment of decision: a reliable person answers the message, a generous one offers the lift. Acting the part first and feeling it later is the normal order, not a fraud.

Write your words down somewhere you will see them. Three is plenty. Then take one small action today that a person described that way would obviously take.
