Non est ad astra mollis e terris via. - Seneca

Aliquid cotidie adversus paupertatem, aliquid adversus mortem auxili compara, nec minus adversus ceteras pestes; et cum multa percurreris, unum excerpe quod illo die concoquas.

Associate with people who are likely to improve you. Welcome those who you are capable of improving. The process is a mutual one: men learn as they teach.

You are doing an excellent thing, one which will be wholesome for you, if, as you write me, you are persisting in your effort to attain sound understanding; it is foolish to pray for this when you can acquire it from yourself. We do not need to uplift our hands towards heaven, or to beg the keeper of a temple to let us approach his idol's ear, as if in this way our prayers were more likely to be heard. A god is near you, with you, and in you. This is what I mean, Lucilius: there sits a holy spirit within us, one who marks our good and bad deeds, and is our a guardian.
