A point to bear in mind perhaps when taking family member or friends for a ride with that shiny new license is that you can feel much more nervous yourself sometimes when relatively inexperienced and with the added burden / responsibility of taking passengers.
Its perhaps not a bad idea to do one or two local flights on your own, or better a cross-country or two with a fellow pilot after getting your license just to consolidate.
Another tip is that I (still) use much greater safety margins for go / no-go decisions when flying with friends / family / other innocent victims(!) than when flying on my own or with another PPL. I think it just gives you a bit more cushion mentally when things don't go to plan.
