Everyone has a dream. Big or small, feasible or unrealistic, but it is there. Do all our dreams come true? It depends on many factors: on what a person is; B on the environment in which he lives; from the upbringing he was given in childhood and from the people who surround him. The more ambitious a person is, the more resolutely he goes to his dream. History knows many examples when people faced countless insurmountable obstacles, but did not give up. They kept going forward, despite the difficulties, until they reached their goal. It is enough to name such names as Lincoln, Beethoven, Einstein, Edison. What helped them and many others to achieve their dreams? There are some practical tips that will help anyone who wants to be successful. First, believe in yourself. Never listen to those who say you can't. Having overcome self-doubt, you are able to do everything in your power to succeed. Second, don't forget that achieving a dream is a process that involves hard work and perseverance. Last but not least, don't be afraid of setbacks on the way to achieving your dreams. Never say never! The day will come when you can climb the highest mountain or swim across the ocean!​
