IMO, Best answer to this question is - It Depends.
And its not just months/ years... I would say even lifetime. Some people are just don't get it. They can't learn from their mistakes, they can't analyse what they doing and don't have the discipline the commitment to improve .. so they will never get it..
Don't compare yourself with others. Compare with your own performance of last months. If you are making less trading mistakes this month, if you are not repeating your mistakes, if you are showing the discipline and following the rules.. then you will make it..
I also made the mistake of focusing on my P&L in earlier days.. and was happy that I was making money.. but realised later that it was not the best measuring criteria in intial stage..It is easy to make profit in a month even by breaking all your trading rules.. i.e. by "flipping coin" style of trading..(maybe one just happen to be lucky in a particular month or mkt was kind) but that will not give the consistency.
My suggestion, focus on mastering the art and science of trading, risk management, trade planning, letting your profit run and cutting your losses, confidence in your trading rules.. Do it so much that it becomes second nature to you.. And.. once u get the consistency..Money will follow (and loads and loads of it)..
All the best.. and happy trading.
