You are not accidental.
Existence needs you.
Without you something will be missing in existence and nobody can replace it.
That’s what gives you dignity, that the whole existence will miss you.
The stars and sun and moon.
The trees and birds and earth - everything in the universe will feel a small place is vacant which cannot be filled by anybody except you.
— OSHO, OSHO ZEN
That is the whole point in the movie 'It's a Wonderful Life'. We have no idea what or how we have touched people in our lives those we know or think we know, those we may encounter that we don't know even.
