Pretty much what I had in mind. Start with enough that I won't be upset if I lose it.
My suggestion is to read One Up on Wall Street by Peter Lynch. He is known for his "invest in what you know" approach. Warren Buffett always said he would not buy stock in a company if he didn't understand the business.
With the exception of a few small investments (amounts I'm okay losing), I tend to follow Buffett's advice:
>>>“Consistently buy an
S&P 500 low-cost index fund . . . I think it’s the thing that makes the most sense practically all of the time.”
And he suggests staying the course, despite market fluctuations. “Keep buying it through thick and thin, and especially through thin,” the chairman and CEO of
Berkshire Hathaway said with a laugh.<<<

I'm not sure if a personal anecdote about how not to invest in stocks will be of use, but here goes.
About 20 years ago I got the itch to invest in tech stocks. My strategy (which was trendy at the time) was to identify an emerging technology that had a huge upside potential. I then selected 5 smaller companies that appeared to have a good chance of being the "winner" in this area of technology. The basic idea was that the stocks of at least one of the companies would hopefully take off and the gains would far exceed any losses on the other stocks (i.e. try to buy the next Microsoft by casting a wide enough (but not too wide) of a net).
After doing my "research" I bought stocks in the 5 companies. One stock briefly took off like a rocket, but it crashed shortly after that. In short, I lost about 80% of what I put in. Fortunately, the amount I invested was very modest, so it was not a significant financial hit.
Here are my not so earth shattering takeaways from this.
First, there's a big difference between reading up on a company's products based on a few press releases, online articles, etc. and actually knowing a business. I thought I knew enough about the technology and the companies, but I didn't. It's hard to know what the real state of affairs is in a small startup company that is trying to puff up it's share prices. Their supposedly hot new technology may actually have almost insurmountable problems, but the company is not going to advertise this (Theranos comes to mind as a rather extreme example of this). I will also admit that some of my "research" was chatting with my buddies about hot stocks over a few cold beers. This is not a formula for success.
Second, there just aren't that many future Microsofts, Amazons, and Apples out there. Trying to identify these companies early is like trying to find very tiny needles in a huge haystack. Perhaps there's a reliable way to consistently pick them, but I have yet to find it. Index funds cast a wider net and they catch the dogs, but they also catch the high flyers.
This is not to say that investing in individual stocks can't work, but I'd advise doing your homework if you go that route.
