Tons can happen depending on your approach. I allocate half my money into companies that are fundamentally cheap and in my opinion mispriced, and the rest are blue chip and fairly stable dividend payers. You can also take the diversified etf and index approach and just forget about it and over time youll do very well. Whats important is not to sell for the wrong reasons, things can drop 10-20% even though fundamentally all is the same or some temporary fluff has occurred. Almost every position that ive made 25-100% has been down at some point by atleast 10%.

Just remember not to sweat it, things are pretty much the same in your life whether you have a 25k portfolio, or a 250k one, doesnt make much of a difference if you keep adding and reinvesting. At some point youll be able to use it but its likely decades away for you.

Made my first 100k at 27. From 20-26 i had a good job and only 10k to show for it, but i moved in with family and got a second job and within a year i had 100k. Next year i hit another 100k, and 3 months after that 300k because of investments i made the previous year.
