The advice I am going to give is that you should look at the mistakes you made before.
You should try to understand what made you lose. You have had such experience and you will have to use that to your advantage.
When you have understood what caused you to lose, then you start looking for the solution and how to do things better next time so you don’t lose money again, and even if you’re going to lose, you should at least be able to reduce the loss. Study everything that needs to be studied and develop your strategies that will help you make more profit in the market.
This is the best advice there is out there. People keep talking about watching stuff and reading stuff and learning stuff and yeah they are right in a way that you can't get better without doing any of those. However one thing is for sure, you can't make a profit without actually doing, if you do what you need to do that means you are going to learn and without doing it you will only have some theoretical knowledge and that is not good enough.
After you start doing what can help you out even more than learning why you lose? It is the best method and people will be profiting a ton by losing, yes that sounds weird but the greatest thing to teach you how to make less mistakes is making mistakes and learning from them. Eventually it is going to be easier and easier and easier and that way you will end up being one of the best traders out there, all thanks to learning from mistakes.
