To enhance your overall awareness, take a few moments every day to observe your surroundings in detail. Example: Notice the structure of the leaf, and sometimes the colour of the painted wall.
Always work with an active mind and try to recall every memory whenever you get free. For example, an urgent informative call or dialogue in any movie.
Don't go for passive reading; instead, indulge yourself completely with an article or a book, pay attention to each word, and summarise the whole paragraph once you get done with the reading.
At the end of your day, recall your whole day, and then try to analyse the main learning of your day. Recalling and writing down these details strengthens your memory and enhances your ability to remember information.
If you need to remember specific information (names, facts, etc.), practice repeating it mindfully. Instead of rote repetition, focus on the meaning and context of the information as you repeat it.
When someone is speaking, give them your undivided attention. Eliminate distractions, make eye contact, and truly listen to understand, not just to respond.
When trying to remember something, create a vivid mental image associated with that information. The more detailed and engaging the image, the better you are likely to recall it.
