Doing paper trade after becoming a trader may be because of not following your trading plan properly. You may think your trading plan is wrong and you want to find some other suitable trading plan. The real thing is your mind dont know how to handle fear or greed. You should feel confident to overcome fear and greed. You have to find you strength and weakness in trading. You are the only one who can find it. Nobody can find it for you. Some people will be good in trade using levels, fibonacci levels or in finding divergence in indicators or pattern finding etc. You cant become master in all. But once when you are clear about your strength you can control your fear and greed. It wont happen in a single day. And the whole process takes time depending on your hard work.
PS : I am always fascinated in oberserving human behaviour and mind. And share market reflects human mind set.
one more point i would like to mention is that a trader has to deal with not just fear and greed - but ego as well - this comes generally when you are successful to some extent - that you begin to believe that you have figured out how the market is going to behave and tend to ignore the rules that gave you the success in the first place - often resulting self-sabotage
