Asking questions will likely prove that you don't have all of the answers--and that's okay. Even the most successful leaders embrace humility and acknowledge that they need a trusted team to figure out the best path forward.

Practice the philosophy of "hire the best and trust them." We need to empower our domain experts to make decisions and sometimes "disagree and commit." Or more often, express our point of view and then defer to the domain expert or functional owner.  This takes humility.
