Social capital.

Σημ.  In sociology, social capital is the expected collective or economic benefits derived from the preferential treatment and cooperation between individuals and groups. Although different social sciences emphasize different aspects of social capital,  they tend to share the core idea "that social networks have value". Just as a screwdriver (physical capital) or a university education (cultural capital or human capital) can increase productivity (both individual and collective), so do social contacts affect the productivity of individuals and groups.

Μνήμες πραγμάτων που συνέβησαν σ' ενα κόσμο που υπάρχει μόνο στα "τι θα γινόταν, αν;".

Time present and time past
Are both perhaps present in time future
And time future contained in time past.
If all time is eternally present
All time is unredeemable.
What might have been is an abstraction
Remaining a perpetual possibility
Only in a world of speculation.
What might have been and what has been
Point to one end, which is always present.
Footfalls echo in the memory
Down the passage which we did not take
Towards the door that we never opened
Into the rose-garden.
