The other day I've seen a trailer of a series on Netflix - Mars Generation, I think? I couldn't even finish it, because when I saw those kids doing the things I always wanted, it made me think about all similar realizations - that e.g. my university started doing things with rockets and satellites just after I graduated, that left and right I see cool spacetech opportunities offered to students only, etc. I'm having a hard time dealing with the fact I was just born few years too early. It's a stupid, irrational jealousy.
