Yeah I can do this. And am not even 30 yet.

Nope.
It would probably help if phone calls still really existed as a method of getting stuff done but the amount of places not bothering / having automated / foreign staff for their call centers makes them basically pointless and a completely different skill set compared to old school charisma and phone etiquette.

Patience and stubbornness to deal with the bullshit and still keep the effort applied will win.

Not some skill that feels nostalgic and forgotten like phone calls or cursive will save you from the onslaught of time.
