#652CPR. Basic first aid. When your child or spouse is choking, bleeding, or unconscious, you will not care about anything else.

#653Setup and learn how to use Anki to practice spaced repetition. Going forward you can now decide what you would like to remember (so long as you are willing to spend 5-15 mins a day reviewing)! People's names, that command you always look up, your credit card number, interesting statistics (e.g number of passenger miles per death for bicycles vs cars vs planes) foundational facts in your field that will allow you to p…
Anki is the compound interest of learning. It makes learning far more rigorous and less stressful and makes it possible to remember things years after you've initially memorized it.

#655On the contrary, it has taken me years to unlearn compound interest. When you start with relatively little, compound interest is relatively very unhelpful - it compounds wealth and benefits people who have started with something more than you. Twice as good at nothing is still nothing.
Alright, I'll bite. This is such a victimhood mentality and a ridiculous statement. I wasn't wealthy when I started investing. Hell, the first dollar I put into my long term portfolio was when I was living in my car! I started with ~$200 that I made from doing a collection of odd jobs (mowing lawns, computer repair, moving dirt, etc.). Every extra penny I made went into investing into a moderate portfolio focusing on…
Calling someone being poor a "victimhood mentality" is possibly one of the most privileged, out of touch things I've seen on HN.
Why don't you go tell all those families on welfare to just go make more money and change their mindset.

Nice personal attack. Your anecdote is nice, but is that is all it is.

#657Understanding compound interest thoroughly. Compound interest is probably the most powerful "force" governing out lives. It is crucial when borrowing money, especially for longer terms. It is crucial when saving and investing. It is crucial in self-development, where a tiny 5% improvement in some area of your life per year can mean that you are twice as good at something in 15 years. It is important when evaluating a…

One of my favorite Charlie Munger speeches seems relevant [1]. > I have a friend who carried a big stack of linen cards about this thick, and when somebody would make a comment that reflected self-pity, he would take out one of the cards, take the top one off the stack and hand it to the person, and the card said, “Your story has touched my heart. Never have I heard of anyone with as many misfortunes as you. Sure, yo…
That's quite a concerted way of displaying his complete lack of empathy. Imagine if he put the same effort into bettering humanity rather than chasing wealth and snubbing nose.
Are you really implying that Charlie Munger hasn't bettered humanity? He has given money generously and created wealth for countless people.
It's not lacking empathy. At the end of the day the only thing you can remain control of is your attitude. Are you going to let unfortunate circumstances continue to ruin your life or are you going to do something about it? Charlie developed this thinking when he son died of leukemia at age 9. He was devastated, but he decided it wasn't going to be a drag on the rest of his life.

The 'rule of 72' is a quick and easy rule of thumb to determine how long an investment doubles, and improve how you think about compound interest. For example it takes approx. 10 years to double an investment at 7%, or 7 years at 10%.
We are currently in a world where it is very difficult to find interest rates >2%. I found a tezos staking pool at approximately 5% recently.
It's not specific to interest, it works for any compounding percentage, include stock or real estate appreciation.
Of course, past performance is not necessarily indicative of future performance. But as a mental arithmetic trick, the rule of 72 generally works.
