Dog Days (and unfavoured earth-inheritors)

My brain is strange, and pairs seemingly (somewhat) related sayings to reach strange conclusions. For example:

1. Everybody gets their 15 minutes of fame
2. Every dog has its day
CONCLUSION: dogs get to be famous longer than humans. (is this because of a temporal approximation of dog-years?)

1. Fortune favours the bold
2. The meek shall inherit the earth
CONCLUSION: fortune does not favour those who shall inherit the earth. (maybe by the time the meek inherit it, it’s all skludgy and barren? do the fortunate inherit better planets?)
