Unprepared for volatility

I made a mistake of not adjusting my size to volatility. This would be perfectly ok for half size trade but not for full size. That drop was hitting at morning lows and it could go either way and market was very fast. Luckily it finished well but it could have been costly.
After few days of constant winning it's easy to just drift away and not pay attention. Only to get awaken with big loss somehow showing at charts
