Every incidence provides experience

Every incidence in life; good or bad - provides experience.
Every experience shapes our future thoughts and perceptions. 
Every day, we face many different situations, and go through various different emotions. 
Some experiences leave such deep impressions on our mind that would either confirm or change our previous perceptions forever. When a similar situation or incidence, or the same person provides us a different experience at different times, our thoughts, perceptions and ideology changes according to the new-found facts. We have continuously witnessed this fact in the study of science, especially in past few decades - particularly in exploring the space. New theories are found and then rejected almost every month, after observing or discovering some new evidence. 
Same is true with individuals and groups - corporations and organizations. Their thinking and ideology also keeps on changing with the time; based on new experiences and circumstances.
It is said that ‘Change is inevitable.
Nothing remains the same; everything keeps on changing.
That is why – to describe the world or the universe in Sanskrit, the ancient Indian scholars selected the word ‘Jagat’ – which means ‘constantly changing’. Just like the universe keeps on changing, our perceptions of the universe and everything in it also keeps on changing according to our own personal experiences.
