With the right attitude, self imposed limitations vanish

As for a limit to one’s labors, I, for one, do not recognize any for a high-minded man, except that the labors themselves should lead to noble accomplishments.

Your ancestors came to Macedonia and the rest of Hellas [Greece] and did us great harm, though we had done them no prior injury. I have been appointed leader of the Greeks, and wanting to punish the Persians I have come to Asia, which I took from you.

May God keep you away from the venom of the cobra, the teeth of the tiger, and the revenge of the Afghans.

Youths of the Pellaians and of the Macedonians and of the Hellenic Amphictiony and of the Lakedaimonians and of the Corinthians... and of all the Hellenic peoples, join your fellow-soldiers and entrust yourselves to me, so that we can move against the barbarians and liberate ourselves from the Persian bondage, for as Greeks we should not be slaves to barbarians.

Toil and risk are the price of glory, but it is a lovely thing to live with courage and die leaving an everlasting fame.

Every light is not the sun.
