I started the same way than you 25 years before. Yes, it is a bit dry, but imagine how hard it was before the internet

Can only recommend you to keep on going this way. The thing you need to learn is to understand a company and the market. Choose very little stocks, max 5.

Start a investment book. Write down all the numbers you can get about the company, quarterly results, annual results, forcasts of the analysts. Try to figure out what numbers you expect from them next year, what P/E you can accept and if it is very high, why in that case you can accept this high P/E. Is your last assumption still valid?

Apart from outside factors like market situation, interest rates, ... , there is one basic rule:

A stock will grow if it performs better than the analysts expect, it will fall if it not meets the analysts forecasts.

Another thing is that you cannot ignore a supertrend, no matter what the numbers say.

No matter what you think of Apple, you need to go with it (I would never buy their products, never had one, but the stock is a must)

No matter what you think of Tesla or BYD or E-Mobility, you need to go with it.

No matter what you think of Covid 19, what vaccination you want to take or not take, you need to have the Biontech stock.

Actually as stock investor the first thing when you hear about something like Covid 19 is "Who will make billions out of this and how I can get my very small piece of the cake"

Sure shots like Biontech are very rare, mainly it is the tough work mentioned above.

Forget about books nowadays, internet has it all. A good website I like to work with is simplywall.st
