How about you giving me some tips. that's good money for adsense.

I guess you just increase your traffic organically.

I agree to both of the people above as you are still getting a decent amount as adsense is no more providing such good amount of $$ per day.
Some old people are still having this amount because you high amount of UV's per day so just try not to get less thn $40-50 per day as its still a good amount and it would be good if you can share some tips as well.
Thanks

that's good daily earning. Congrats. How about installing tell-a-friend script on your site?

If you are really making that much per day from adsense and you need help, the only place I could possibly direct you to is your local psychiatric unit. Those results are awesome.

Seriously though, the only tip I could lend with results like yours is to build more sites using the same model as the one you currently have. 5 times the work you're doing now would make 250.00 per day. Since you already know what to do, outsourcing your work is a realistic prospect, which leaves you to basically oversee the admin of your sites and collect your money.
