1) This is very common problem, everybody has problem of information overload. Its not possible to read all the book, read all the blog post etc you get the idea. We are always worried by not reading a particular book, we are missing on something important. Our mind try to deceive us whenever we are doing something that we are losing on something else, it will try to bump some idea so that you get off the work, its afraid that he might lose the control on you.

Solution: The main point here is taking back the control, when you are doing something and your mind tells that you are missing, or I have this another great idea. Ask him objectively what is the great idea or what I am missing, if he can answer your question, write it down in your notebook and politely say to him that I know you are trying to help me, I have duly noted down your suggestion / idea will work on it once I am done with the current stuff I am doing.

About books , blog , videos etc, I know I can find the something useful if I go find the dustbin again. The idea here is pick some gem, pick your books / blogs very acutely. Now trust that the book you are reading is sufficient and good and if you need to know anything other than this one, you will bumped by difficultly when you will be needed to know. I think the whole problem arise when we try to use books as Textbooks not as helpbooks, when we try to find the exact method in books not direction where to go from current situation.
