Ad astra per aspera.
"To the stars through difficulties" or "To the stars in spite of difficulties."

The motto of the state of Kansas, USA and Campbell University, Buies Creek, North Carolina, USA.

This motto suggests that we achieve great things only by encountering and overcoming adversities; it will be rough going, but we will make it.

ad augusta per angust
To honors through difficulties.

Augusta refers to holy places, angusta to narrow spaces; therefore, sometimes we can not achieve great results without suffering by squeezing through narrow spaces.

ad perpetuam rei memoriam
For the perpetual remembrance of the thing.

These words are traditionally used to open papal bulls.

Ad virtutem per sapientiam.
To virtue through wisdom.
