I'm 23 (almost 24). I believe that all human beings go from birth to death in one and the same way (I mean from psychological and physical points of view). My belief is in science. So, I wanted to know what I'm likely to expect as I grow older. I wanted to learn it from some great and most complete textbook on the psychology of human development (or how to call it?), but didn't managed to get the full electronic version of it
But apart from textbooks, I think it would be wise to ask people in their late 20s, in their 30s, 40s, 50s, 60s, etc. what they could advise to younger people. I'd like to know what I may miss, what I'll definitely encounter, what mistakes are inevitable, how I will feel at certain age, what I'll think, what my emotions will be, what my delusions will be and so on. Please, look back at your past, remember yourself at different ages and tell me just everything you find interesting and worth mentioning.
