Funny thing about kit building is the number of stories about building 2 port side wing panels or same side fuselage halves I've heard of.
I am sure I silently told myself that this could never happen to me, but some how I've managed to do this too.
Slow but steady wins the race, rehearsing the next step in your head before actually taking it helps keep your efforts moving towards the goal line.
Congratulations for deciding to become actively engaged in this adventure...!
