SENECA

• Study groups are powerful.
• Read the whole thing & then reread and understand each paragraph, one by one.
• Sleep well, have a good rest for your memory.
• Write notes during the class, then relook at them right after the class to give it depth. It will not work if you do ...

You could go your whole life waiting for certainty, that ONE thing and risk never finding it. 

Many people go this route, and it's ok if this is your case, as long as you full-well understand the consequences (never finding it).

The most important thing that keeps our lives in a flow is constant learning. One should study and read whatever possible, engage with others, ask questions, and never stop evolving.

One has to always make an endeavour to leave other people in a better condition than they were before.
