I am ruthless with my tabs. I always close them all at the end of my day.
Just like Inbox 0, I aim for Tab 0. Serenity is the reward for this small disciplined effort.
Close them. They're not going anywhere. You can always find the links back tomorrow. An entire multi-million industry wants you to find them back as easily as possible.
You might even find better ones when you start fresh.
It's just your loss aversion instincts kicking in[1]. It's how your brain is wired. But we live in the golden age of information retrieval. You don't need to hoard tabs. Your brain just doesn't know.
Trust me, if you can. Close them.
It will be ok.
