Yet, in the same way that you wouldn’t set out on a long journey without consulting a map, we all need to have some idea of our destination and how to reach it.
Eto, yn yr un ffordd na fyddech chi’n cychwyn ar siwrnai hir heb edrych ar fap yn gyntaf, mae’n rhaid i bawb ddeall i ble maen nhw’n mynd a sut mae cyrraedd yno.
