First of all, understand that losses are a necessary part of any risk taking activity. The goal should always be to blunt the impact of losses as opposed to eliminating the losses altogether. There is a distinct difference between minimizing the impact of losses versus minimizing the number of losses. If the money you are risking stands between you and hunger, think twice before placing it on the line. Risk capital must be true risk capital.
Second, losses are better teachers than wins. As noted above, wins often lead to complacency. Losses usually compel you to figure out “why.” If small and incidental to your overall strategy, they confirm that your plan is working. If relatively outsized and/or unexpected, losses make you examine the precedent trades and determine if your strategy should be adjusted. This is how advancement happens. Thomas Edison needed nearly 10,000 tries to find filament for an incandescent bulb that would last for more than a few hours. Of the thousands of attempts that did not produce the bulb, Edison did not see them as failures, but rather as things that didn’t work which was useful knowledge in and of itself. By knowing what didn’t work, Edison was able to find his way to what did. Containing and then examining your losses will help you do the same with your trading strategy.
Third, recognize that losses that are kept small relative to your portfolio are a big part of the fuel that propels your account higher. They say that you are taking prudent steps to grow your account… that you are “in the game.” The alternative, especially if you accept that losses are a necessary part of trading, is no risk taking or the taking of outsize risk (refusing to cut losers). Neither of these provide a path to account growth. If you can find/develop a trading method that allows for (in fact, embraces), many small losses while still delivering profits overall, you will have gone a long way toward eliminating the trepidation that most new traders feel about entering the fray. You will also be able to stop worrying about having the “right” picks.
The more i trade, the more i realize that trading with big size is just stupid. Sure, you will have your occasional huge win. Sure, there are a rare times when trading with size is good to capitalize on ‘easy’ trading setups but i believe that 95% of the time trading with size will surely lead to over trading, micro managing, flinching at the smallest wiggles, lead to emotional decision making, stressful trading and burnout.Trade small positions and you will see how you will think more clearly, you will stay objective, you will stay calm under pressure, you will trade less and ride out bigger 
Stop trying to be perfect. Great trading is not about perfection, it’s about probabilities. If you go to a restaurant and order a steak, you don’t need to eat the bone, gristle and fat to enjoy the steak. And you don’t need to sell the top or buy the bottom to make a killing in the market. Just look for the sweet spot and dig into that. If you leave some profits on the table, that’s ok. You’re still going to leave the table feeling confident, in control and with a full stomach.
This is not going to endure me to my fellow traders but I think it is important that we all are reminded what the market promises us.I am not talking from my gold and diamond encrusted throne. I am not exactly killing it. I am not perfect; I do not make money every trade or every day. This is a reminder to me, more than a reminder to you.
