I think it was life timing along with the introduction of DMT into his life, but SWIM has changed his life quite a bit of late.  He is more concerned with being a good person than with actual business/financial success.  He has also taken up yoga and has stopped abusing alcohol.  I don't think DMT gets all the credit, but I don't think it hurt either. 

I believe DMT may have helped to remind SWIM of some universal truths that he already knew, but may have forgotten as they were pushed further behind the vail of the ego...
