Many decisions to make on what I should do ?

Would you say it be more profitable/ productive

as well as be more worthwhile to me - overall to make up my Own

Affiliate directory & put it on my website OR to join a few “Good”

programs & promote them on my website ?

I'd say promote some stuff.

With a directory, you're hoping that people who want to sell will join. That doesn't mean they'll do anything from there, however.
