Writing things down to remember them, you feel like you've dealt with it. Which can be a great help since you can empty your brain of distractions that pop up and do so in a way you feel you've not just forgotten something. And reread later you'll realise how little was really important outside the moment it came up.
But if you place an artificial burden on yourself to follow up on everything that might be interesting, then that's probably overwhelming and shows a lack of prioritisation. That might be due to a lack of a system to prioritise, or it might be a lack of goals. Asking why you do it might feel you work backwards towards the goal - is it an ambiguous sense of professional development, or is it simply an enjoyment of pursuing novelty that means you keep turning up things that you feel you should come back to, but because novelty is the goal you never do. These might miss the mark with you, but they explain for me a lot about why I do the same things.
