"Keep constant guard over your perceptions, for it is no small thing you are protecting, but your respect, trustworthiness and steadiness, peace of mind, freedom from pain and fear, in a word your freedom. For what would you sell these things?"
— Epictetus, Discourses
So how do you protect your peace of mind as a trader?
This is quite simple really from the outside looking in. Stick 100% to the rules/criteria for your strategies, without deviation. Concentrate fully on your own trades and not what all the others are doing. Otherwise, you will become indecisive and flit from trade to trade and end up jumping on far too many trades that you had no intention of even looking at, let alone trading! If your trading becomes dysfunctional, you then start trading with emotion as things start to go wrong and you will end up undisciplined, impatient and you certainly won't have the correct mindset for trading!
So stick to the plan 24/7 day in day out; become almost robotic as you do the same thing over and over again, rinse and repeat. This is the way to success.
Yes, it may be boring and easier said than done! You may want the thrill of jumping on other people's suggestions; but it will be to your cost and detriment and you will be blaming everyone but yourself for your inability to stick to the plan that you know works for you long term. By constantly sticking to your rules/criteria for your strategies, you are taking full ownership of your own trades and nobody else's. This also means that you are trading patiently with discipline and ignoring the noise of others, therefore ensuring that you have the correct mindset to protect your peace of mind.
If you work hard at achieving this, it will become second nature and a natural common practice.
You can do it for sure!
