Cross & Gospel should satisfy you, calculations must include [God]+2+2, serve God unwaveringly & worry about nothing else, Christ makes up for you being a zero in finance/sociality/virtue/talent, remember Ignatius ignorant/penniless/persecuted/slandered yet loving & believing to great effect, God always uses inadequate instruments & requires only docility, no difficulty can shake your optimism given to God, only totally given can you expect to win others, ignore the contempt of powerful people who change often, so-called prudent people attribute madness to God's work, unite with brothers to carry out God's will over all obstacles.
