Always avoid overtrading
This is something that I didn't had control on. When I started trading, I used to keep on checking the prices to see if I had made any profits. Whenever the price used to go low I would panic and start selling which eventually resulted in loss in most of my trades. This is why I left trading.
Absolutely vital to hold yourself in bearish market and making sure you don't get over excited and over-trade during the bullish market. I have had the same problem when I was new because I was a BTC price trader initially and I used to get so excited that I would buy more and more bitcoins during a bullish run and then obviously at some point the bullish market will stop and I would panic and sell the coins.
This also had to do with faith because when I was new to the bitcoins world I never knew if bitcoins would be 0 tomorrow morning and hence when it started to fall down I was so worried that oh no the time has arrived. Now, with time I have realized that bearish rounds will come and bitcoins is never going to be zero ever.
