How do you manage your time online and make sure you're spending it on something useful?

If I'm being honest, I'm online (and on PC in general) more than is healthy. Never less than 12 to 14 hours a day.

In practice, I use it most often for:

– creating graphics

– creating videos

– gathering ideas and creating content

– LinkedIn (this is partly work, but also entertainment – and I can easily spend 3 hours a day there

– exercise (I work out following YouTube videos)

I'd say productive use is around 60 – 70%.

But I want to reduce the total time overall and shift more toward productive use: work and learning new things.

To monitor my PC activity, I use @SurfPal – I found it on PH (which only shows analytics of where I spend time and how often) and Activity Monitor within Mac.

But still struggle to find a time for learning / replacing my unproductive or work time with learning, because I work so much that I do not have time to learn.

How do you keep your time under control, and how do you "force" yourself to use your time online more efficiently?
