In life, there are a lot of keys to success which includes determination, ambition, patience, and so on.
Determination is one of the most important and best keys to success. Determination makes you focus on your goal and no hindrance will make you back out. You believe you have to do it to make your life different (positively).
Ambition is more or less like determination, but it is not only for yourself, but for others benefits.
Patience is always needed in whatever you do. For instance, a farmer who wants to harvest his produce will always wait until they are ready. Either one or two years they would still wait. This makes them see a lot of gain from the produce and it is not only for their benefits, but also for us. So please in what ever you do always consider patience.
Never let anyone know your plans in life. Not everyone is like you. Your friends are not praying for you to be better than them, but for them to be better than you. Telling anyone your plans is the same as telling them what you intend to do in the nearest future. They may use that as an advantage over you.
Whenever a person tells you everything about him or her, just know that such person is rare and no one can replace the person. If possible, get closer to the person to know or make the person trust you.
Friendship is a bridge to success and it makes you have someone to help you when you need to succeed.
Lastly, never let anyone discourage you in what you intend to do.
