Germany overwhelms me a bit.
Philately can sometimes overwhelm the best of us, especially world wide collectors.
It is such an enormous jigsaw, one sometimes wonder where to begin.
I have boxes of stamps still unopened after 10 years.
I bought when prices were low,
I underestimated what a job it was to catalogue and mount all the issues.
Just take it a step at a time, if it loses the fun aspect, take a rest.
