I think the parent's posting is more applicable than you might think - putting in the effort to go on dates and really get to know a person does a lot to cultivate romance.
Nothing kills romance like hanging-out, but my perception might be different than yours - my ideal romance leads to a life-long relationship, which takes the same kind of effort that the parent's suggestion called for (deliberate effort focus on a romantic relationship).
This is... not exactly actionable advice for everyone ?
