To Make Any Gain Some Outlay Is

That Which You Know, Know Not; And That Which You See, See Not.

Every One Can Remember That Which Has Interested Himself.

No Man Will Be Respected By Others Who Is Despised By His Own Relatives.

Unexpected Results Are The Rule Rather Than The Exception.

There Can Be No Profit, If The Outlay Exceeds It. [non Enim Potest Quaestus Consistere, Si Eum Sumptus Superat.]
