> A lot of what we want, what we perceive as living a full life, having fun and so on comes from culture (and increasingly in the last decades/centuries, with mass media).

This is very important. I didn't figure it out until late in life, and wasted a lot of effort and money that could have been better spent.

When you want something ask yourself "why", then ask yourself "why" about your answer as well. Keep doing that until you hit bottom and its usually something like "so other people will think more highly of me."

Whenever you find yourself with "impressing others" as a motivation, ignore it. You'll learn to care less about what others think about you when you realize how seldom they do.

And don't forget, that sometimes day dreaming about going to space, might be more fun, than actually going. It's not like you can touch it anyways.

My point is: Remember to enjoy your dreams. And 99% of the time let them be just that: "dreams".

Yeah, this is why it's important to block ads from your life wherever possible. Other people profit from telling you what your dreams are.
