I've done the same with writing books, participating in adventure race sprints, and learning new instruments. I didn’t say, “I’ll try,” “I’ll see” or “I want to do that.” I affirmed that I already had the ability to DO it. If you read motivational and self-help books, they give the same advice. Speak as if you've already become or done that thing.
Start telling yourself, “I can do that.” Go out there and DO IT!
Leave me a comment on a time you did the same. I'd love to hear from you, and you might inspire someone else to live their dream.
