If you are anxious or worried about a position you are either over position or don’t believe in what you are holding. 1. Manage position sizing (never exceed more than 5% of your total position on one trade) 2. Only buy companies and projects you know for sure are going to be around and grow over the next decade.
Every great investor I have ever listened to says that when times are bad, and things are down, and everyone is running scared, that is when they doubled down and made the majority of their money.
Proverbs 13:11 “Wealth gained hastily will dwindle, but whoever gathers little by little will increase it.” Slow, steady, patient investing (like long-term compounding) is biblical. Get-rich-quick schemes are not.
