One thing may entail another either of two ways: simultaneously or subsequently. Thus learning entails knowledge subsequently, and health entails life simultaneously. Conversely, expectation entails disappointment, with frustration as one of its byproducts.
Do not expect so much from anyone, not even your most trusted allies, you are bound to be disappointed when you do so; people are rarely at level you think they should be. When you overestimate anyone’s capabilities or competences, the outcome is always a disaster, pay attention on the person you have direct control over, which is YOU.
Again, do not expect so much from politicians, or look towards them to solve problems, it’s a misconception; politicians do not solve problems, honourable/noble people do, and you rarely find them among politicians. The little good things politicians do come out of compulsion, it is not in their nature to do good. For your own sake and wellbeing, always lower your expectations when politics is involved.
For politicians, it’s about talking before thinking. So it’s very easy to promise free health and education, even when you don’t know what the costs are, let alone sources of income to make such fine promises a reality.
Your boss or manager can disappoint you, same goes for your employees, expect a shock anytime you overestimate one’s capabilities.
