My first big lesson: The allure of 'just a little more'

Hey everyone, just joined the forum and figured I'd introduce myself with a bit of a cautionary tale, as requested. Been trading for a few years now, mostly focusing on forex pairs like $EURUSD and $GBPUSD, with a dabble in crypto like $BTC when the setup feels right. My biggest early mistake, and one I still have to guard against, was the 'just a little more' trap.

I remember this one $EURUSD setup, beautiful pin bar on the daily, clear support/resistance. My initial entry was solid, and the trade was moving perfectly. I had a target in mind, but as it approached, I started thinking, "What if it just goes a bit further? This momentum is strong." Instead of taking profits at my planned level, I moved my take profit, then moved it again. It seemed like a genius move right up until it wasn't. The market reversed hard, blew past my original target, and ended up hitting my stop for a small profit that was a fraction of what I could have had, if not a scratch. The lesson burned into me: stick to your plan, and never let greed convince you the market owes you 'just a little more'. It's always best to capture the setup you planned for and move on, rather than chase those extra pips that often evaporate.
