Frustration in Forex

In my experience even with a plan and strategy it can still be frustrating, although not nearly as much as without those.
 
Some traders suffer frustration when the price is always opposite from their orders. If entered, buy price quoted is heading to the bottom.
It they entered the sell price goes up.
I think this is due to lack of experience and knowledge in the business.
What do you think?
Would agree, experience is key
