It's significant that this quote is taken from 'Acts'. Too often, when it comes to giving, people take the easy way - they dip into their pockets.
Real giving means that you forget about yourself for a while and your energies are engaged in 'action' for the benefit of others. When you do good things for others, you will find yourself viewing the world differently - you focus on the positive difference you can make, rather than just seeing the bad. Such immersion is a sure way to experiences those moments when you are so absorbed in something, everything else is forgotten, and afterwards you feel great.
There is a positive link between kindness/generosity and happiness. Research show that people who engage in activities helping others are happier and report a greater purpose in life than those who engage mainly in pleasure-seeking activities.
A truly generous person does good without expecting anything in return. They don't do it for praise or acknowledgement. What they get in return is greater happiness. There is something known as the 'feel-good, do-good phenomenon' (Salovey, 1990), where being happy inclines a person to be more generous, which in turn brings greater happiness.
What goes around comes around.
