Not having consistency and discipline isn't the disease, it is a symptom of not having a real edge. So when you are trading, you are like a feather in the wind, being tossed around by emotion because you don't trust what you have.
Once you do have something that repeatedly works, you will be amazed how disciplined and unemotional you become. That is why there is a whole industry surrounding trading psychology, because the methods that retail traders use are at best statistical (all systems are statistical unless you are a criminal and have inside information that you use, it is a matter of how much - you don't want to bet on the outcome of a roulette wheel unless you get money odds, which no one will give you), and 90% or more of them are of negative expectancy.
What does it take? I will give you one piece of advice:
1) stop wasting time on retail trading sites like this one looking for help. 99% of the TRADING advice you will get are charts and nonsense. The people that don't know, talk and talk alot. The people that know don't talk. Go and work at an institutional firm and see how they trade. No one is going to hand you anything in life, unless you were already born on third base.
Easier said than done, because it is a self-selecting system of people with huge ego and lots of money and the ability to hire really smart people. That means if you are an army of one, you have to be all those people in one! "You've got the brains, I've got the looks, let's make lots of money..." That's it. Once you understand, then come back and pay back as best you can by helping someone else with what you have learned.
If that is not an option, then all that is left is:
2) Trade as small as possible, trading instruments that "hurt when they fall on your feet". Avoid [and I mean like Ebola] any instrument that gets coverage on television around the clock like stocks or stock futures or stock index futures. Concentrate on markets that are absolutely critical to the functioning of the world. For example, oil, or other critical commodities. Gold is NOT one, but Copper is. Possibly Interest Rates, but that is much harder. FOREX is fine, but the hardest of these. Once you pick a market, learn everything there is to know about it. Then you are crawling at least...
