Staying motivated when Your MVP isn't gaining traction

I am aware that achieving success with a project involves numerous key factors. One of the challenges is attracting new users, and it's common to experience a dip in motivation after a few months. So how do you stay motivated and continue pushing forward when your MVP doesn't meet the expected success in the initial stages?
