Confused with 'promise' - 'promising' describes potential, while 'promise' is a commitment., Using 'promising' for things that are not likely to succeed., Mixing up the forms; saying 'promise' instead of 'promising' when describing potential.
Usage notes	Use 'likely' to express probability in neutral contexts. Avoid in very formal writing; use 'probable' instead. For informal contexts, 'likely' is suitable.	Use 'promising' to describe something that has potential, particularly in business or personal development. It's not appropriate for things that are guaranteed to succeed.
