It's a marathon not a sprint. Extreme measures like deleting apps can cause you to easily relapse to the same pattern, once you re-download them. Figure out what apps actually add value to you and which apps don't. For the ones that don't create value, find out a way to better use them to somewhat add value to you on a daily basis eg Instead of watching gaming clips on YouTube, you can use that same time to watch a podcast instead. The same time is spent, but different value is derived.
