It will benefit you to keep your plans for a better life to yourself while you are growing into you position. There will be plenty of time to talk about your success once it has actually taken place. The time to tell them about your goals is after you have achieved your goals. It is not worth risking the chance of some miserable individual trying to discourage you from doing something you feel in your heart. If you keep your goals and intention statements to yourself, people are less likely to try to stop or advise you. Only reveal your intentions and goals to people who need to know or can help you realize your goals more quickly.
Share your intentions with only those who you know will be supportive and encouraging. Share your mind only with people who are worthy.
