Rwy'n credu ei fod o gymorth i ffermwyr wrando ar rywun sydd wedi gwneud camgymeriad ac sydd wedi cael profiad personol o'r hyn all fynd o'i le a chanlyniadau hynny.
I think it helps for farmers to listen to someone who has made a mistake and has had first hand personal experience of what can go wrong and the consequences of that.
