Someone said to me recently, 'nothing/no-thing matters; i.e. when 'no-thing matters', when we don't worry too much and don't try to force things, all possibilities remain open/available, since they only crystallise into actuality (matter) when we focus on them..so, focus on negative outcomes, worry and those will 'matter', become solid or actualised immediately and restrict the chances of a positive, beneficial outcome.
In effect, we have the good grace to allow God/All That Is to choose with us, in the wisest way, from the maximum number of possibilitiess available. We truly participate in the choosing from that 'spacious present' and then we don't limit ourselves - when 'nothing/no-thing matters'!
