Is clinging the reason for losing interest towards certain things?

We lose interest to certain things (foods, vehicles .. etc.) with time. Is clinging the reason for this ? Is this the nature of clinging ? Are we able to maintain the interest level if we don't have clinging ? Does losing interest to do something (working on a project, studying, new year resolutions, etc.) means that I had the clinging to that thing (or end result) initially ?
