Slogans are all very good, but if we are bombarded by them, or just with the passage of time, they can turn into clichés that no longer serve their original purpose. Other things can happen, like they can start to mean different things to different people (e.g. insiders vs outsiders), which again cause them to be ineffective or worse.
We sing "We want Moshiach now" and put slogans on yarmulkes and elsewhere but what does it really mean? Indeed, we mention it so often in shmone esrei that most people just rush through it without thinking twice, and others need convincing that the desire for Moshiach is not exclusively Chabad's. Certainly saying something (different) about Moshiach & Geula on a regular basis can help break the rote patterns and actually get us thinking.
So I was very excited to read an article about a lease for an apartment in Jerusalem that has a clause allowing the owners to terminate the lease when Moshiach comes. Clearly this is someone who not just believes in Moshiach's coming, but has prepared for it by purchasing a place to stay in Israel, and making sure they can move there when he comes! This is inspirational on such a practical level.
There are other ways we can think practically about Moshiach. A businessman can consider if their business or industry or market will still be around in Moshiach's times. Some industries may quickly disappear, but others may boom. Students of scenario planning will recognise the disruptive nature of Moshiach's arrival, and can consider the impact on the external environment.
We don't know much about how life will change when Moshiach comes. The Rambam has a few things to say, but still leaves plenty (particularly timing of certain things like techiyas ha'meisim) to be resolved at the time. It's one of those things where we don't know what we don't know.
Humans have inertia, and we have developed a comfort zone around galus (2000 years will do that). Thinking in very practical terms about how disruptive Moshiach might be to our everyday lives is quite scary, but if we *really* want Moshiach, then surely it makes sense to prepare practically for his arrival.
