Is there any method or recommendation on how to setup the right Contexts? I used to have "standard" contexts like @Agendas, @Call, @Computer, @Errands, @Waiting, @Home, @Office. But sometimes I feel that they're not right and I think maybe I should create something different that would be connected to places I'm at like @Office, @Home, @Car, @Shop. But I could be wrong again. Is there any methods?
