Well I have a great system that I sure beats everyone else here.
I have a (Real) notepad with 20 pages full of shit I should do now/should do in the future/ shit I could do in the future/ random ideas/ great porn quotes to use on websites/ lists of my paysites, content ideas/ random phonenumbers, all that is listed in my notepad and on ripped out pieces of paper from that notepad, the ripped out ones are the important ones.
Pretty hightech shit eh? I really don't think a PDA could ever compete
I just do what works for me. As long as your productive and making loads of cash its all good baby ;-)
