Default Tasker profile management

So I've been using tasker for a while now and it truly is an.impressive app.*
But since I've been using it a lot I've got lots of profiles and tasks as a result of playing and experimenting and learning.*
So I've decided to start over again!

My question is. What's the best practice for usage / profile management.

My goal is too have tasker automate basically everything. So....

I'd have a*
home profile
Tasks to set volumes, turn pin off, turn Wi-Fi on, etc
But also within the home profile I'd like to have it set volumes based on time, i.e night time, and daytime and reduced volumes.

Work profile
Tasks to set volumes etc

Car profile*
Connect to Bluetooth, change screen timeout. Etc

What I'm.struggling with is keeping it tidy.*
My current setup doesn't work as it should, and I think its due to the haphazard profiles. For example I have a car mode which should disable the pin. Which it does, for a while.But then the pin comes back on due to my gone profile becoming none active.

Can anyone help me on how to best achieve solid and clean profile management and prioriTizing
