There is a reason why people say we shouldn't expect too much. No one wants to see someone they care about and end up disappointed. We Instinctively act to protect our own from being hurt and do what we can to make the right choices for the people we love. But the reason we have expectations in the first place is because we want to aim as high as we can because when you love someone there is no limit to what you can accomplish.
So keep your expectations as high as you - that's the Real Mantra For Life!!
