Working towards your dreams is difficult.

Working towards your dreams is one of the most difficult things to do. There will be times when you just want to quit, you'll wish you hadn't started and you will feel like the weight of the world is on your shoulders.
Remain focused and strong because once you achieve your goal and look back on what you have been through, you will realise that it was worth all the sacrifices you made.
