I am almost satisfied with the adsense income compared to my traffic. After all it is the income from my hobby and not my Job
Reason why people are not happy is because they don't have patience, perseverance, and dedication to make long-term earnings... Adsense is not a quick easy money... you need to invest time to earn long-term..
Thank for all your comments! For those who are not satisfying, plz google & search some tips to increase your earnings.. You know everything is free.... but only to invest your time & efforts..
