I know someone will ask so here is a brief meaning...
Success: attaining a positive personal achievement
A newborn baby; posit the wisdom or sage advice that would be forthcoming from this young individual if he/she was able to tell about the secret to living. Perhaps the answer might be along the lines of 'see teat and suck it'. Usually though, it's been my experience that secrets about successful living are passed down, not up. Although there are exceptions no doubt.
Should we heed someone's secret to life or shove it aside to find things out for ourselves? I'll give an example and tell me what you think. My since departed father told me once that the secret to living successfully in the real world(post education) was to get out of the high school mode of thinking as soon as you can. OK, I was in high school at the time so I thought he might have had too much to drink that night. However I heeded that advice but I'm not sure if I did it consciously or not. It worked for me. Are secrets to living coincidental with age? IOW some secrets only mean something when you are old enough to understand them.
