This is the virtue that requires total selflessness. If in any way, you intend to have some personal gain from your act of generosity, that act is no more a liberality. Some people tend to be generous in order to gain respect from people. Some exhibit the act of liberality with the motive of having some political influence in future. Some display the act of liberality just because they love to be called a generous person.
Whatever the case may be, the phrase "generous person" is a difficult name to maintain. Humans are quick to forget the past good deed. The moment you are not able to give at the moment someone requires your help, the adjective generous attached to your name will be erased, forgetting the hundred times you have been giving him in the past. So even in your act of liberality, wisdom is required.
This wisdom is a simple one. That is, your act of liberality should be from the purest of heart. And also knowing that charity begins at home. Any act of generosity done by a person that cannot be Corroborated by the family of that person, such act of liberality is questionable.
That act where you want to share that little you have with someone, not necessarily because you enough or much, but because sharing with someone, gives you fulfilment and happiness. That's what liberality entails. And the world is in dare need of the act of liberality.
