I tend to not hold onto spot positions well, I want to sell as soon as it goes up a little; futures are even worse, I get itchy and add some leverage, and the next thing I know, I get taught a lesson.

Later I understood a piece of advice: don't let the "part that might lose" affect your sleep.
Basically, treat your position like a volume knob, turn it down when the market is noisy, and only turn it up slowly when it's quiet;
Before entering, assume the worst-case scenario, losing only enough for a takeout meal, then you have the qualification to keep watching those large transfers on chain screenshots, otherwise your mindset will blow up early.
Recently I saw people complaining about validator income and unfair MEV ordering, and I feel it's better to be more conservative; when rules don't favor you, fighting against them is just money out the window.
That's all for now.
