NEVER be fomo
1. After sprt.com lesson that caused me 200usd ( not a alot to most, but yeah),  I became more cautious about the market. And don't buy and hold just because many said so.
NEVER be greedy.
2. Break even, and go. Don't wait for it to rocket. If you know the outcome of the stock, you most probably won't be here reading this.
UNDERSTAND your buy
1. Read up unless you are very aware of what is happening
UNDESTAND the financial of your buy.
2.Look at the cash flow of the company, understand it.
End of the day. We can't determine the stock. Trade safe.
