I think people shouldn’t give up on their dreams so easily.
Dreams don’t gome true over night. You need to work really hard for them. Never, ever should you let others to hold you back.
In the end, you live your life for you, not for the others. They might laugh at you. But in the end you will be the one to laugh.
Most people are afraid to dream big, let alone go for their dreams. They are afraid to fail. So they might but you down for taking the risk, they will never take.
You also need to understand, that you need to work really hard. If you fail, try again.
Let your dream be your lantern in the dark.
