Good on you for reaching out Padi. You deserve a response that's more than a one liner.
Plateauing results are a thing that happen and will keep happening. One of your many jobs is to identify the limitations by being very honest with yourself in all aspects of your performance. I have always done it through a journal and weekly reviews with incredible results. It's allowed me to objectively view my trading habits as a third person and take the appropriate action to consistently grow. A great place to get professional in this area would be SMB capital.
If that's to new age for you and you prefer to be toughnut then you'll have to look at others ways your habits are slowing you down. But I don't think introspection can or should be ignored. Do this at your peril and your P+L will beat you into submission. Traders with large starting accounts can very easily hide behind the account size.
Of course none of this will help if your strategy or suite of strategies aren't well designed, tested and measured.
For me the 3 biggest things that were holding me back by not allowing replicable and scalable results were:
Outside distractions (kids)
Experimenting too much 80/20
Living off my profits at the expense of my account growth (stagnation)
The solutions were not instant fixes but auto trading was my answer to both scalability, replication, perpetual growth and controlling my work hours. I then moved to experimenting only 10% of the time because I could see through my measured approach that I was actually extremely profitable with the bread and butter trades but was using that money to explore my curiosities. These changes fixed the capital allocation very fast indeed and I've previously posted about how I take profit.
You will obviously have a different set of paradigms to sort out but maybe not so different. The process of continuously identifying and ridding weaknesses is a constant. So you need a process to pick this up during some form of quality control in your production output. One cannot underestimate the impact having kids will have on your trading life (was it you who asked the other week?), but you can front run it as with many others factors that can have an impact on your current methods.
One thing is for sure, if you man up and face your deepest fears as trading will show you and methodically move through and measure the process...you will surprise yourself and gain a trust in your ability to to overcome adversity. Every time.
