positive impact

Do things for other people that will make an impact on their lives, simply because you want to!  - the last 4 words are the important point “Because you want to”  it is no use doing it out of a sense of obligation or duty, because that will only make the action counter-productive.

Next – seek to develop friendships with new people, they may have something to share with you that can have a profound effect on you life or similarly you may have a major effect on their lives.

Remember, a small impact on someone's life can sometimes be more effective than a large one.  You don't have to give money but a gesture or a kindly word will often be significant and mean a lot to the recipient.  Give willingly and freely, expecting nothing in return and you could well be surprised by what transpires.
