Ignoring losses is not a permanent solution to the problem. You have to find the root cause of the issue and eliminate it. If you find an issue in your trading plan, change it with something that works. If you find an issue with your emotions, you better take breaks after losses. This will give you enough time to do introspection and gain more confidence to come back stronger. Also, it will give you some time to relax and get rid of the stress that you have been facing because of failing trades.
