I can pretty much average $40 a month here on Clixsense, according to my stats. Other success stories on ClixSense have described members cashing out a total income in the $100s or even $1000s within 3-5 months. But yes, it does take some considerable amount of effort if you want to make big cashouts here on ClixSense. You certainly can't leave the site and expect your balance to grow on autopilot.
The best thing to do is the paid surveys, because they accumulate on your balance very nicely if you can average $1-$2 at the least per day. Tasks are just too convoluted and time consuming, so I don't bother with them much, unless it is the simple "review Casino site" tasks.
Viewing all your ads each day does add up too. If you can build a huge referral base, that would be really fortunate. You might also want to upgrade to Premium, because with this membership, you get more ads to view and exclusively earn commissions as well as the Daily Checklist Bonus.
You can tell him all of this.
