I have had good experience using CJ they pay well and consistently. Im sure there is lots more I can do to increase my earnings if I concentrated on it full time, but for now I just do what I can when I can.

Affiliate Marketing takes a lot of perseverance!

Totally agree with you. Perseverance, perseverance and even more of it. That's why I gave up. I prefer selling advertising selling advertising space directly to publishers.

Also how can you trust them, I mean affiliate programs?

Yes, you are right, I have also heard in some forums that people are earning good money With CJ also, what you need to do mainly is to build that kind of website which sell products mainly..
