There is nothing wrong with being dramatic occasionally! I wish there were a real science to help us understand ourselves more reliably too - but there isn't. But maybe we are slowly entering the enlightenment after the dark ages of psychology?

I think in today's world it is easy to become a cynic, and being a cynic is one way to feel safe. Depending on what your utility function about the world is, being a cynic might actually be the most "rational" approach to life - new things are more likely to fail, and if you always bet that something will fail, or is flawed, or worthless, or a scam, you will be right more often that you will be wrong. In the right circles you might be considered a wholesome, grounded, put together person if you are like that.

But perhaps we could get the best of both worlds? Have a little corner of your garden that is entirely dedicated to experimentation with ideas - keep them there, see how they interact with a sampling of your actual garden, and after you feel confident enough, promote them to the real garden, and let them nudge your life a little. If it turns out for the worse, tear them out and throw them,
