Sometimes it gets really hard when we are going after our dreams, and it makes us question whether or not we are meant to do this dream.
This is a very natural conversation to have with yourself. It completely makes sense. We hit a brick wall, and we think it's a sign that means maybe we just weren't meant to do this. But if you desire it, if it's in your heart, that's all you need to know that you ARE meant to do this.
There are many famous failures - like Harry Potter. 12 publishers turned down Harry Potter before it found a home. That's a lot of rejection! J.K. Rowling could have thrown in the towel and convinced herself that she wasn't meant for success. But she kept going, and thank god! I love those books and movies!
