If you could start your collection from scratch, knowing what you do now...

I would focus more on quality than quantity. Remembering passing up on a E121-80 Peckinpaugh due to price and fact I thought I would find it at the National. I didn't find it and later found one on EBay but not near the quality. Also, no more cards missing large areas of print on the back. I was lucky and was able to sell these off at a slight loss. Quality is very important!

On the whole, I have few regrets. There were a few bats that I passed on 20years ago because they were asking $100 more for them than the going rate, and these 3 or 4 bats (or others like them) haven't surfaced since. And there's a few high end bats that I didn't notice going up for auction that I wish I'd seen and that have also not been offered since. But, for the most part, I've got a lot of great bats at very fair prices through simple perseverance.

If I could go back in time and restart my collection based on what I know now, I would would collect American gold coins.
