Delete your brokerage app
Seriously. Some of y'all -2% complainers need to just delete your investing-ahem, gambling -mobile app.
Seeing red every day will make you sell a quality business for a loss. I've found that focusing on the fundamentals is far healthier than the price. Literally just read the headlines, but don't check your stock, analyze the data for what it is, and not for what the market prices it to be. Morningstar is a great example of this. Get a library card, and then you can access their NVO report for free!
This saying goes both ways as well. Be cautious if you are getting excited over a 5-10% pump (in our case, almost never XD) because then, when the stock is not pumping 5-10%, you'll ask stupid questions. And those stupid questions will lead to stupid decisions.
For reference, I own 67.## shares at an average cost of 50.##, which is 25% of my portfolio.
Buy, HODL, retire. It will take a few years for our bullish thesis to play out. If the movements are too much to stomach, throw 10-15% of your porfolio into as something stable like SCHD.
