It’s okay to be influenced by someone skillful and responsible trader, because you will definitely learn a lot of positivity about trading from him. But if you were influenced by a blind and pretentious trader, believe me everything he said might be too good to be true, and you both end up having miserable trades and mess up with your finances.
However, whether you trade by influence right now or not, the most important thing is you do your own part as a trader. You acquire your own knowledge, you develop your own skills and strategies, and most importantly, you gained positive traits out from your trading experience.
Emotions are your enemy when trading, but if you are responsible on managing your emotions, you will definitely succeed on your trading career.
