Nobody Can Replace You But You
Some people may think that there are plenty of people who can take their place. However, this is not true, as it is based on the idea that humans are like machines, replaceable.
For example, at work, if a person leaves, it is sometimes necessary to replace that person with another person to keep the whole operation running.
However, to say that there are many people who can replace you is to miss the point. Even if the job is done, it is impossible to say that the person who replaces you will do the same job as a copy of you.
People have different personalities, different life experiences, and even though they may have similar roles in their work, no two people in the Universe are exactly alike. The individuality that is given to each person is unique.
When we view people as mere cogs in the wheel, as inorganic things, we lose sight of what is essential.
There are things that only that person can do. That is what each of us is created to do. They are not something that can be duplicated, but rather each of us has an individuality that is irreplaceable.
There is no one else who can take your place but you.
