If you fail it doesn't mean that you will always fail there's a time that you can change to be better. As they always say there's a room for improvement. If you fail once it doesn't mean that when you try again you will again fail. for me the world "try again" means that there's a chance that you will succeed.
You can succeed if you strive harder for it to happen and you have perseverance sometimes you need to wait to see the result just have patience and wait for your reward.
Put in your mind that in life you will never be on top there's a time that you will fall and you need to stand up on your own the people around you is not always there to help you.. Learn to stand on your own sometimes they will help you but remember not all times they can help you.
