My guess is that rather than "always be thrifty", this is more like "don't let cost-optimizations stop forward progress". So, somewhat more like "penny-wise, pound-foolish" or "don't let the perfect be the enemy of the good" than "always be thrifty".
Master wedding-feasts
My guess here would be a meaning like "take full advantage of important ceremonial celebration feasts", with possible connotations of both "enjoy them fully" but also "don't over-imbibe or take them for granted".
Grieve for no one
Could very well be dependent on the exact form of 'grieve' in the original formulation; if a word meaning to mope or remain backward-looking (as opposed to honoring/learning in memories), it might really be about doing the right kind of mourning. Or, if the emphasis was on 'one' unique person, it might mean never to focus grief on any singular loss, as loss is universal – sort of related for "ask not for whom the bell tolls – it tolls for thee".
