What if you were more intelligent? What would you do with it?
Would you even notice a difference? How?
In some ways this is both really simple and really complex at the same time. I think it's not possible to actually possess or obtain more intelligence, but that we can experience greater or an enhanced access to intelligence at various points of our life. In some ways I'd want to continue doing exactly what I am already doing, but with greater freedom and with a bigger "reach." I suspect there would be new ideas, too, that I didn't think of before.
For example, I would like to help solve some of the food, water, and climate issues in the world. And let me set out by saying that I believe these are very connected to humankind's collective consciousness about life, and that I have no intention nor desire of robbing humankind of its necessary growth and development regarding these. But, let's say with current intelligence I could be capable of going to a foreign country and help plant crops. Let's say with some increased intelligence I could go to the foreign country and design a new system of planting crops that was never thought of before, and was of greater benefit to the people. And let's say with a further increased intelligence, I could actually make it rain. And with more intelligence I could actually just manifest bread in my hand to feed a multitude. And with greater intelligence still, I could not only manifest bread, but could teach classes on how other people could manifest bread. And still further intelligence I could just have another person manifest bread and know how they did it. Etc.
