Because someone doesn't see your dreams as possible, doesn't mean they aren't. You are you and they are they and they cannot live your best life for you.
That there is some rich and true quote and I wish more people can learn to see themselves in the light they are really made up of.
We all live to learn and as long as we interact, we will always have something new being added to us.
Keep the faith and never live your life on someone else's terms.
Stay Awesome!
