You know that thing you’ve always wanted to do? You can do it. It’s possible. This is the 21st Century. Anything is possible.
And if for some strange reason it turns out to not be possible, it just wasn’t meant to be, but you will have learned a hell of a lesson trying to make it happen and you’ll be able to apply that lesson to something else and it will probably work out for the better anyway.
Don’t ever not do anything because you thought it was impossible.
