This is my opinion, from my own experience and knowledge of the subject from executing many operations.
investigate and have knowledge of the company that we are going to buy, its stock or currency that you are going to trade
be analysis of graphs and know how to read trends.
trust yourself and do not copy others, because the other can be wrong.
be patient not everything is now, sometimes you have to endure so that you can reward it.
have continuous monitoring of price values.
have a strategy, not everything is crazy, the best things is to take things slowly and think before acting.
not having emotion and having a cold and calculating mind, everything is going to happen only is to be a calculating person.
always be aware of everything new, news, technology and more. the more updated the better.
have variety, not commercial with only one I recommend having a portfolio of investment variety.
the most important thing to have a fixed-paying job to invest, do not put all your money because you can risk losing everything.
This is what I learned from my experience, I hope these things will help you because it has helped me to know what to do in each situation.
