Only you can choose to do something meaningful or not. Every person is capable of doing acts of kindness. How many good deeds can you do in one day? 1, 3 or maybe even 5? The more good each one of us does, the better and more pleasant our world will become. —————— Need examples of good deeds? - Give up a seat to a pregnant woman while in public transport. - Help a senior cross a road. - Feed a homeless animal. - Do not throw away old clothes. Rather give it to organization that helps poor people. - Call relatives or friends who you haven’t been in touch for some time. Signs of attention always lighten up the mood. - Throw garbage in a proper place, not at random. - Wish a good day to a shopkeeper or simply smile at a stranger on the street. The more smiles surround us, the brighter and colorful our world becomes.
