I wish I had an answer for you. I feel like I am missing something big here but just not sure what it is. My weekend goal is 90-105 and my weekday goal is usually 120. I barely make it most days. I also only get one round from TTG but she is not there everyday. LTG is hit and miss also. Only reason I met my goal yesterday and today is cause nGage came back. I went through two surveys, both through the demographics, only to be credited 1sb. Done, done, and done with surveys...otherwise I might hurt someone lol...I don't understand how people post they get 250sb's before even leaving for work. I couldn't get that if I sat on SB's all day and did nothing else.
During the week I don't have a ton of time to be on sb but can get between 200 and 300. I do survey's but that doesn't always mean I will qualify for one and have been doing less of them lately because I can't sneak them in at work on my phone and the apps have been running well at work so I do them instead. I do the apps for 60sb and any bonus they may give. I do the three daily things for another 4 unless the daily crave doesn't want to cooperate. I play swagasaurus for 10sb. The rest come from ncraves and watch lists, though I am getting a bit less on the watch lists now that they have lowered some of them or added more videos to the lists. I rarely do search because I rarely get points when I do. I do LTG in the morning before work, though he has been cutting me off between 8 and 12 lately.
For me a lot of it is that I'm either on the computer or I have it there while I'm doing other things. I'm working on my volunteer stuff on the computer so I can get watch lists going and change them and ncraves when they are done. I'm reading a magazine/book, folding laundry etc so I have them going and keep an eye on them. It keeps me from keeping my nose in the book too long, which is why I have needed glasses/contacts for distance since I was 12, so it's actually a good/helpful thing for me

Keeps the eyes from getting worse when I focus on other things once in awhile.
Try the survey's in peanut labs, you are less likely to get kicked out because it has filled before you are done or at the end from demographic changes. You can get stuck in a survey funnel but you have to realize that and know when it's time to stop or to try and keep going. They all ask questions to decide if it will take you to the survey or not, the one that always kicks me out is if I answer that I'm not hispanic. If I answer 'prefer not to answer' it will generally take me to the survey. Then it's hit or miss as to whether you qualify, and when I get to the survey I do fill out caucasion. But at least if it kicks me out at that point I should get 1sb as long as the survey spins it back to PL, which it doesn't always do, but neither do the gold ones.

@wendow I forgot to add that I will sometimes do offers, there's sometimes ones in PL for 1sb that say credit instantly, generally all you need to do is click on them and they credit when the site opens. I also sometimes try ones in PL or on the regular sb page, I'll read the disclaimer to see what I have to do to get the points, click through to something, sign up etc. When offers work I'll post them here as others do and sometimes they work for other people and sometimes they don't. It can be hard to tell if you've done an offer for a place before if it's not a named one, like bing, hipmunk, etc because they change the picture or even the sb credited.
