Is boredom and a lack of desire to spread Islam and show people the right path a satanic whisper or something else?

What prevents a person from doing good are Satan and the soul that incites to evil. To overcome this, one must not respond to evil whisperings and continue spreading good by setting realistic goals and utilizing available means.

First: Strive to seek religious knowledge by adhering to scholars and reading beneficial books so that you can call to Allah.

Call to Allah within your immediate circle, starting with relatives and friends.

Avoid setting unachievable goals so that your efforts are not wasted.

Seek advice from scholars in your country and cooperate with them.

Increase your supplications to Allah, asking Him to use you in His obedience, and sincerely purify your intention for Allah the Almighty in seeking knowledge and calling to Him.
