Focus watching the market price behavior/movement - familiarize patterns
Hit single or double, don't hit a homerun - always have stop and exit
Know yourself - psychology/emotion/temper/impulse/revengeful/rationale/impatient/fomo/greed/etc
Do your own trades - as in 'mind your own business' mentality
Kow when to stop/step back
Don't get influence - no you tube live trading/social media
