it's not so much about how hard it is to do 5 sales/day.. you're setting the wrong type of goal..
you should be setting one or two goals based on revenue and net profit. a sale at at 35pps sponsor and a 50/50 revshare sponsor are totally different, and at AFF, etc.
consider this, though.. if you spent $150 on adwords (just an example) and made $175 in sales.. im sure that's not the goal you had in mind.
i assume your goal was formulated based on something like 5*35=175*30=~5k/mo.
so assuming you need to profit 5k/mo, you need to plan your goals based on that.. so if you think you can get a 50% ROI on PPC traffic (again, just an example).. you'll need to be able to float around ~5-6k in PPC charges to promote a sponsor that pays every 14 days. you'd be spending $350/day to gross $525/day, profiting $175, or ~$5250/mo.
hope that helps, or maybe i confused you even more
