At times, just expressing our thoughts & ideas could really prove helpful for someone else. Each one of us sees & experiences things which are then stored as memories in the form of words and sentences.
Our unique interpretation of a situation/experience could provide a different perspective for others which means, the thought or idea has its own place plus can open up a new array of unique thought processes.
Science, literature, technology, & even medicine were merely ideas & someone’s imagination, as someone began somewhere, just as a thought, just as an idea. Some just kept thinking, lost in their world of imagination to explore & truly know what they see & experience. Some began the quest as new ideas were shared.
