Our own beliefs might be a barrier to achieving our goals. Sometimes we have a fixed attitude, believing that our intelligence and talents are fixed and unchangeable. This might leave us feeling helpless and that there's no purpose in trying. But what we need to foster is a growth mentality, which believes that we can constantly learn and improve. This might provide us the incentive to keep going, even when things get rough. So, if we are always moaning and seeing the bad side of things, we will never be able to achieve progress. Instead, we need to be optimistic, focused, and determined since every successful person in this world has once been a failure before becoming successful so we should grow and focus on our progress instead of being perfect.
