I was told all the same bullshit you’re told.
"You'll never do that."
"Be realistic."
"When are you going to get a real job?"
"You need to start taking your future seriously."
Don't listen.
Just because your goals and dreams weren't possible for them doesn't mean they aren't possible for you.
Have you ever considered the fact that all the comforts and conveniences of modern society were once thought to be impossible?
Phones.
Cars.
Airplanes.
The internet.
Thoughts and ideas that were all ridiculed and laughed at by a long list of people whose names nobody remembers.
Whether other people believe in you or not is irrelevant.
We're surrounded by stories of massive success everywhere we look.
Stories of discouragement and doubt followed by perseverance and achievement of the "impossible."
These stories are what inspire, encourage, and show the next generation what's possible.
It's your obligation to live a life in pursuit of the best story you can possibly write.
Make it legendary.
