The number one tip ☝Omar said it☝
The number two tip is always practice, practice, practice.
I would also advise limit your YouTube viewing and subscriptions to Blender videos. Maybe go further and avoid YouTube and other social media to prevent procrastination. Only go to YouTube tutorials and search for specific Blender topics you wish to learn, avoid all the other fluff that may come up on your feed.
The morale of this story…
Avoid distraction, practice daily even if its only half an hour.
And one more thing…
Look at everything in the real world as if it was a 3d model, imagine how you would model everyday objects and visualize the topology flow.
You do this, and you can truly call yourself a 3d nerd.
