I go for long walks at night a lot. I always manage to find a street that I’ve never been on that leads to some new block of streets or patch of woods that I never knew about. I think it’s something about navigating through a new space; when I’m walking I’m able to figure things out for myself and make decisions that other times I have a hard time with. Usually by the time I come to a street I know and have that “Ah, so that’s where I am” moment, I’ve already had a similar moment in regards to whatever decision I was trying to make.
I used to come up with cool/interesting/new ideas while I was high, but lately this hasn’t been happening, at least not with pot. Other substances I’ve been using do produce cool ideas, but I can’t always remember them.
As for profound thoughts: they come whenever I think. If I’m reading a book, and I stop to pursue an idea that came to me while reading, or if I’m on the bus and I just think, I usually end up with a few good ideas.
