Romans 8:28
We know that in all things God works for the good of those who love him, who have been called according to his purpose.
Do what you love. Don't let anyone steal your happiness. There's nothing wrong with giving up. It's just wrong to give up before you try and give your best. There are no mistakes, only opportunities. Learning is a gift. Even when pain is your teacher. Never let your memories be greater than your dreams.
You have the patience, the strength and the passion to achieve your ambition, your goals and your dreams. All you need to do now, is try.
A happy person is not a person in a certain set of circumstances, but rather a person with a certain set of attitudes.
