To poker players (even traders) I think you've heard this over & over before but I think it still serves as a very good reminder for us because in the field of trading and poker (even athletes), mindset and psychological factor plays such an important role.

Markets are so random (at times) and we should always factor in losses along the way, as long as we focus doing the 'right' thing, we will succeed over the long run!
