Declare your ambition. You don't have to know all the details.
This is Bob Goff's advice in his new podcast, The Dream Big Podcast when chatting with Jason Russell. And I concur!
Being open about your ambition is like throwing a party 🎉. Let people know what you want to do - invite people in! Share your ambition like you are sending out invitations - you don't keep party invitations to yourself! Yes, it may be scary. People may laugh at your proverbial invitation or toss it aside, but maybe, just maybe, they may open the door wider, inviting more people in, connecting you to people that will benefit your new ambition. Friends may even enter the trenches of the behind-the-scenes work and planning, cheering you on!
So let people know. Parties are more fun WITH people and so are ambitions (whatever they may be!) There is power and community in vulnerability.
Now, what kind of party are you throwing?
