You should be willing to do something that will take you five minutes or less for anybody.

Every day, do something selfless for someone else that takes under five minutes. The essence of this thing you do should be that it makes a big difference to the person receiving the gift. Usually these favors take the form of an introduction, reference, feedback, or broadcast on social media. Do something that's not for yourself, every single day. Expect nothing in return. Over time, these random acts of kindness will really add up.
