When I entered into crypto space I lack the gut to invest, I learned a lot over and over again before having the gut to purchase my first BTC
It was exactly the same thing for me, Infact, mine was a bit different cus I actually came into this space through a friend who introduced me to a project then, the project was in their ICO, I knew absolutely nothing about crypto but this friend compelled me to invest in that ico, the project later turned out to be scam, and that was how I lost my first ever investment in crypto, after that incident, I decided on my own learn what crypto is all about, that was how my journey began.
Google is also a good teacher.
Google taught me over 80 percent of what I know in crypto, I even found and became a member of this forum through Google, it was a joint effort between Google and the project I mentioned above, I actually Google searched the project to know what it is all about, that was how I found a link about the project which lead me to this great forum, and later on became a member here.
Today, I am always proud to tell my friends(those who come to me for education on crypto) that no physical person taught me anything I know of crypto today, I learnt everything through research on Google and this forum likewise many other online sources.
Invest only what you can afford to lose, no matter how good a project utility might seem there is a chance of failure in future.
Another simple explanation is "diversify" and "don't put all your eggs in one basket", many people are guilty of this, when they find a project is looks good and promising, they want to go "all in", if anything goes wrong and project crashes, you end up loosing all your money, but when your money is diversified, you stand a chance of regaining losses on a project from another project.
