@jeplet Hard no. Don't invest in individual companies. This is just gambling, which, having just given up two addictions, isn't a strong move. Especially don't invest for dividends. People think it's free money, but it actually takes untaxed capital gains and turns it into taxable income. It's the quickest way to lose 33%. It's just a terrible idea.
You are in a good spot so long as you don't do anything stupid or listen to bad internet advice. Here's what you need to do. Read the Barefoot Investor, then read The Millionaire Next Door. These will explain how to budget properly, set up an emergency fund and why your colleagues are buying nice things. Once you get through those,read A Random Walk Down Wall Street. It's a bit heavy in parts, but that is the only investing advice you will ever need.
If you are a YouTube guy, Coffeezilla, Patrick Boyle, The Plain Bagel and Common Sense Investing are all great.
And if you can listen to things while you get your prep done in the kitchen then Planet Money & The Rational Reminder are great.
Don't jump into anything quickly here. Be slow, be patient, be smart. Good financial advice is generally pretty boring. If it seems too exciting or quick run a mile. Good financial habits are small, boring stuff that adds up over a long time to massive stuff.
