No one else knows exactly what the future holds for you, no one else knows what obstacles you've overcome to be where you are, so don't expect others to feel as passionate about your dreams as you do.
Nobody but you have to believe in your dreams to make them a reality.
You cannot do anything unless you allow your passion to motivate you. People may tell you, "you can do it", "you can make it" "it's possible" but when you tell yourself always " I can't make it", it's your choice that rules everything!
You can go with an empty pocket and come back heavily loaded if you allow your passion to escort you!
