Think on, some are just too serious to talk to, never mind do business with...

Which means:

as the general rule of life often states, those who strive to be first should not have really bothered...

interested only in the shaping of my own shovel and digging with it where I like.

Which means:

Your life is individual to you, by all means learn and use the knowledge gained, but go for doing it your way... I do promise you, your whole life will be more enjoyable for it!...

Which means:

just do it!
