"I have too many ideas, how do I figure out what to do?"

Your brain isn’t meant to hold lots of ideas, it’s stressful.
Create a place to dump all your thoughts and notes ( I use Clickup, it’s great, here’s a referral link with a discount)
Note down all your big picture tasks and todos
sort them by importance.
Set aside a bit of time each day, every day, to work on them.
Little and often is better than grand gestures.
Make sure it’s realistic so you stick to it.
Half an hour first thing every day is better than taking a week off then giving up on it.
