The glass is neither half empty nor half full, but quite simply at a point of maximum potential

Don’t settle for a half empty glass, always go for a full one!

To me, the glass is always half full, never half empty.

I'm a confirmed negaholic. I don't just see a glass that's half full and call it half-empty; I see a glass that's completely full and worry that someone's going to tip it over.

I don't wish to argue,
whether the glass is
half empty or half full,
as long as what it holds,
is pure and delightful.

[If Smith was unsure whether his glass was half full or half empty then his counterpart was also struggling to figure it all out.] I'm happy with the result but not the performance, ... We tried everything. We pressed and pressed so congratulations to the Italian team. We tried many ways to attack but Scotland played well.
