Expectations are, to some extent, self-fulfilling. If you hold a positive expectation, you will be more likely to have a positive result. The mind can be very powerful.
If you know that something is right, Swami Kriyananda says, don't let anything discourage you.
Questions include:
What kind of expectations should we hold in regards to life? How should we approach life?
What if something negative happens in our life?
So if I'm trying to achieve something — it's still a good idea to hold a positive expectation and keep going forward even if things aren't working out?
