Our greatest weakness lies in giving up. The most certain way to succeed is always to try, just one more time.
We show our weakness when we give up on our aim in life. Life without an aim/goal is dull but just having a goal is not enough, we should, no matter how much time it takes, always strive to achieve it. No matter how many trials it requires, never give up. Because whatever effort we put into achieving it will always turn out to be fruitful in the future.
