I think the most effective way to do projects is to do them honestly as if it’s yours. Think long term and highest potential of the project where you can take it and it can take you. Give 110% percent if possible. When multiple people work on the same project and work with people under you, revise their work and trust & pray for them to do the best work. Believe in them, they can help you and learn things that will help them in the future.
