When you expect nothing and receive something, it's such a nice surprise. I'm not saying to be pessimistic. Just when it comes to other people, don't hinge your happiness to expectation and outcome. Don't make it tit for tat. Don't keep score. Don't expect or demand something back. Do the best you can. Work passionately towards your dreams. Be a good person. Liberate yourself from expectation so much that when something does happen: when someone does do something nice, you can be surprised. Celebrate in that joy. It makes it all the more fun when it comes unexpectedly! Expectations in relationships suck all the gratitude and appreciation out of everything. Beyond honesty, respect and basic decency nothing need be expected. Let it occur naturally. Go with the flow. Whatever you end up with will be more honest and real.
