Sankofa is an Akan word and a symbol — most often a bird with its head turned backward, holding an egg in its beak. The egg is the future; the head turned backward is the past. Together they teach a simple, demanding idea: it is not wrong, nor shameful, to go back and fetch what you forgot. The future cannot be built on amnesia.
Se wo were fi na wosankofa a yenkyi.Akan — It is not wrong to go back for what you forgot.
