✅ Meticulous describes being very careful over small details (a meticulous approach to work).

✅ Conscientious and meticulous both emphasize taking care and being detail-oriented (He was very conscientious about minimizing his environmental impact; She was meticulous about making sure her cookies were identical).

✅ However, meticulous puts more emphasis on getting even tiny details perfect.

✅ A direction is a kind of course to follow, generally with a goal in mind (It took us a while to decide on our direction).

✅ A tack is a course of action or approach (When something doesn’t work, it’s important to change tack).

✅ Both of these words refer to an approach, course, or route, especially in a figurative sense.

✅ You would normally use tack when you’re changing direction (I realized my approach wasn’t working, so I tried a different tack).
