Make trades, and it's hard to make money if you stubbornly stick to one model.
Trading should be stable and profitable; don't try to do every model, focus on one trading model.
No need for obscure theories or advanced techniques.
Don't challenge yourself with high difficulties; just do simple trades.
Truly research and understand one trading model in depth, and trade only within that model.
Then continuously practice, perfecting the simple moves, and you'll be close to profitability.
