Hmmm... I think I've had some good experiences on psychedelics, a couple of really amazing trips where I did some good thinking.
I've abused cocaine too much, and spent too much money on it, but I've had some great times, and I bonded with my CEO a year before they offered me a job over a few lines!
Too much MDMA probably didn't do any good for a year or too.
But hey, I did this all while getting my degree, progressing my career, and now I've got the job of my dreams, halfway around the world. I've got a shitload of good friends who ran the journey with me, and a heap of wonderful ones made along the way.
I've got some funny stories, some terrible ones, but all in all, it's been a fucken great ride!
So it's a big fat yes from me.
