If you do, more power to you, but it is just icing on the cake.
That’s exactly where I “plateaued”; when value became more important than the things I loved about collecting, it lost its lustre. My life circumstances had changed; I was saving for a home, and planning on starting a family - and money itself became much more important to me than it ever had been. I guess I grew up...
Still have my favorite pieces, though; it would be hard to part with them.
