Reading your request for advice I found the tag line at the end a little odd:

There are two rules to success in life:
"Don't tell people everything you know."

For me this is sort of contrary to the idea of this community, where people freely exchange ideas and information. Obviously there is the 'joke' element to your statement, however IMHO this is not the attitude (albeit left up to reader interpretation) we would wish the 'newcomers' you mention to walk away with.

Update: Changed 'all be it' to 'albeit' as advised by blyman
