How do I moneitize my videos on YouTube so I don't have to go back and moneitze when I have new videos?

To monetize your YouTube videos consistently, you need to join the YouTube Partner Program (YPP) by meeting the eligibility requirements: at least 1,000 subscribers and 4,000 watch hours in the past 12 months. Once you're accepted, enable monetization for all your videos in your channel settings, allowing new uploads to automatically be monetized. You can also set your default upload settings to enable monetization for future videos. Additionally, consider using other revenue streams like merchandise, sponsorships, or Patreon to diversify your income.
