Read it like your job depended on it,most of the times it does.
This is one area i always look towards improving.Few ways i had come across:
- Reading it in stages : .. skim through first trying just to finish it . Then work slowly in reading the important areas.its important to glance the whole thing through first because you must get an idea that a certain content actually exists and know how to access it quickly.
- pencil n work book :, highlighting/underlining important points.Take summary notes of important , tough,topics.
- Tackling Relevant Areas First : Reading through contents and tackling areas that are applicable immediately to your situation and reading the rest as and when they come.
- Prioritizing Important Areas : Asking seniors on which areas to cover first and making a priority list and tackling it the set order.
- Rubber Duck : Yes It is real and very relevantYes It is real and very relevant.Explaining Tough concepts or reading it out to a rubber duck will help you understand it more.
- Online-References : Find online ,references,examples,real time implementations of tough concepts and mark it down next to the manual.
- Moment to Reflect : After every tough topic take a moment to try to recollect connections,dependencies and visualize the its application,implementation.To really ingrain the concept.
- Find Discussion Group : Forums,groups,colleagues,seniors any one who you can discuss the concepts to keep things fresh in mind and to gather their point of view on the topic. Remember different people understand the same topic with varying intensities and depth based on their experience and exposure.This also helps keep up motivation and interest.
Always remember what RTFM stands for.
