Question: I seem to be the only one in my house capable of putting the remote in the same spot. 

How can I solve the "I can't find the remote problem"?

Answer: 
I think you can try tie/glue/tape a piece of string to it and tie the other end somewhere near your couch, or wherever you sit to watch TV. If that dangles too much, maybe you can try fixing one of those retractable lanyard thing to your remote so it doesn't still end up at random places because it will retract to that one spot.
Rather than attaching something to the remote, make a place for it that is more attractive/easy to use:

Various places sell sofa-side magazine holders, or trays. Have one of these on the most useful end of the sofa. Use tape to mark out a silhouette of the remote (or remotes, as many of us have) and tag it with the name of the remote.

This should help encourage usage. To further help, why not gamify the process, with points for each member of the family who places the remote correctly or loses points for failing to do so. Top points at end of week wins a prize.
