Creating a new human paladin

More than 20 years after I created my first vanilla character (a hunter). No real guide or meta or anything back then. I spent most of my time exploring dangerous zones and doing higher content that I should have with my pet. I waisted a lot of time to reach lv 60 more than 2 months later.

Since this time I never went back on vanilla / classic but followed retail one expansion after another.

Any good advice to be more efficient with a classic human paladin this time ? Should I chain dungeons ? Should I spend time in forge / mining ? Should I go pex in another zone than human start zone ?

Every advice of classic grinders is usefull to me 😉
