Yeah it’s hard without true belief, but there are differences too. Some you will have an arhat teacher who can’t be questioned barking orders at you so you’re rushing, some you’ll be repeating the same word from scripture for weeks. Living right by the morality standards is step 1 before meditation and deep study. You have to take part in devotional and community based action. But I visited a monastery where it was middle aged dudes were cutting down trees with a chainsaw, who then stopped to talk with me, and they were hard working but laid back. But some places are going to be telling you to work hard and not waste this human life,
But there’s plenty of western Buddhists who did spend years as monastics and didn’t have bad words, Stephen batchelor famously became a Tibetan monk for a decade. You just have to be able to work hard really, wizzies wanting to escape in to the culture and are willing to just flow with the religion and cosmology will be ok. If you go and say “I like it here” then that’s enough. Reading scripture and washing river bowls isn’t that bad if you have the peaceful inclination.
Now depressed dysfunctional wizzies might struggle, culture change fixes some depression lulls in energy, motivation, or malaise but for some it does little. The environment, community, cultural artifice surrounding, may replace a lack of motivation for some - but the extent it will drag you along … eh. Some cultures will do that, but often where monasticism is a requirement for young men for a couple years.
It’s worth trying it if you’re out of ideas and have the energy, lots of variation.
