What do you think of my plan to replace my addiction to social media with a different addiction?
Why would you want to develop a new addiction?
I don't like being addicted to social media. So, I want to change my addiction to something else.
You are not helping the situation by replacing one bad habit with another one. It would be best not to have any addictions at all. There are many resources to learn to develop discipline so that you can overcome your bad habits.
That would be hard.
You're right that it's not easy to get over addiction, but it's a good thing to try to change your bad habits. Your life will feel much more fulfilling if you are able to kick this addiction and lead a more balanced life. Replacing your social media addiction with another will just lead you back to the same place you're at now.
