Low Dose MDMA as Nootropic?

I started doing training and implementations for various telecommunications systems. I have since branched out into other areas of consulting. Lately most of my demand has been in the professional certification space. When I first started out, American Express gave me a blue card with 0% interest for 2 years, and a $20,000 credit limit. I had reached my limit on it within two months of getting it. I had spent something like $19,850. They called up and said they needed to see more tax documents and proof. I refused, and told them I was within my terms and had not broken any rules. They agreed, but did not think I would spend so much so fast, so they shut off my card. No big deal, I had 2 years to pay it off before it went interest bearing! I left the whole balance on that card until 5 days before the APR would retroactively jump to something like 15%, then paid it in full. I used that card, along with a couple other cards to fund my startup. Within 6 months of starting my business I could operate on cash only, and have ever since. I did not pay a dime in interest!
