I found being "current" helped me relax more when flying. Not doing long flights, just flying often, and getting to the point where becoming a pilot becomes like being a driver of a car - jump in, checks, power, lets go...
We dont think twice to jump in the car and hurtle 70mph down the motorway, with many things to hit, but yet we are fearful of flying and controlling a plane (even after 100 hours total time!) and currency is the key (or at least it was for me!).
Also doing the ATPL Ground school - knowledge = confidence (not cockiness, more a knowing)...
