Never Giving Up!
Life is going to find ways to test you. At times, you may even feel that life is unfair. The urge to give up and quit at this time are at their highest but don't give in. Whatever that goal/dream may be, if it's important to you then fight for it. Remember that there is more than one way to achieve your goals and dreams. If one way doesn't work, change your strategy. Never giving up doesn't mean you keep doing the wrong things over and over again, it means to be smart and figure out the correct strategy to take and then making them until you achieve said goals or dreams.
Perseverance, dedication and hard work pays off no matter how many obstacles or bumps come along the way so never give up.
