You look for job, that's what you do! If you feel you're not working at your optimal then for the sake of a steady career growth, you should keep an eye for a prospective role that wouldn't make you feel bored.
If you're in a situation which has the following requisites and it is seldom that you're free to that extent then you could try playing some mobile games or try dating someone to keep you engaged, atleast that's what I would've done.
