I’ll try to explain it simply.
A Lakewood yeshivish person…
1. Places learning Torah as the highest priority with anything else a distant second.
2. Attempts to limit his contacts with the secular world to the minimum.
3. Does not approve of secular studies that are not essential for parnassah.
4. Does not attach value to material possessions or accumulation of wealth.
5. Displays absolute loyalty to the Roshei Yeshiva and mashgichim, their hashkafah, and their guidance in all matters.
