One thing I have learned is to do things for others, yet expect nothing. That’s right, you need to rely on karma. Do good deeds and you will be on the receiving end in the future.
Connect people. Refer people. Forward that article you know your colleague, friend or family member will be interested in. Send a card or a letter – you know, the way we used to keep in contact before email and texting – and handwriting it may be good for bonus points too, i.e. know your audience. Or send a gift just because or just because you saw something you knew the recipient would appreciate.
And when other do these things for you let them know you appreciate it. It both closes the circle and starts the circle anew again.
Try it and see what happens.
