Im lost

Okay quick background summary: I haven’t started trading / or demo trading but I have been doing research on understanding Technical analysis and price action for 1-2 years. I’ve come up with multiple strategies but I can’t seem to find one that is consistently profitable on a monthly basis. I constantly develop strategies that are over a year are profitable in 8/12 months and then lose money in the other 4 months. And in those losing months the strategies is facing like 7 losses in a row with a drawdown of almost 20%. I can’t help but think that my inability to execute strategies that constantly perform well is due to my lake of knowledge of the market and hence I am seeking for advice about potential books, YouTube videos or other educational resources I can look at to enhance my skills. Also, are there any concepts in particular I should look at? FVGs? Liquidity sweeps? Indicators? Trading
