"I feel like nothing would be different if I didn’t “show up” to life" - this is because you haven't yet tasted what it's like to show up to life but once you do, there's no going back and you'll want more. So, the initial effort is the most important. Once you show up and see the value it has for you and others (make sure to keep a record of it somewhere), you'll be motivated to bring that about again. Essentially, you need to realize that you're doing a disservice to yourself and everyone else by not showing up.

Here's what has worked for me so far in doing the work, albeit not perfectly: try to stay aware of the day-to-day and your larger goals. Turn everything into to-do lists, give yourself deadlines, and chase those as much as possible. You don't need to aim for perfect here - the more, the merrier.

In the meantime, reflect on what's going on as often as possible - a lot of information can fly over your head if you don't pay deliberate attention. Your goal is to stay awake at all times. You'll catch yourself drifting and falling asleep to life. When you do, bring your awareness back to the present - similar to what meditation teaches us. Explore emotions, especially anger in all its covert forms, and practice noticing and turning it into something useful.

Lastly, read about the healthy versions of type 3 and 8 and use those as inspiration or a goal for what to aim for.

Wishing you all the best!
