what is something i can invest in that doesn't require me to put a lot of money into it from the start?

Answer 1

Mutual funds are a easy way to start but before you start investing make sure you have money saved for emergencies like job loss or illness. That way if an investment is down you don't need to sell.
The very easiest way to save is a 401K plan at work you start with nothing but just fill out a paper. They will then take an amount every payday or a percentage of your pay to invest. Some companies will give you matching funds or profit sharing so your money grows faster.
With any investment you have risk the more the potential reward the more the risk. You can expect to lose money some years and make money others some investments have great swings. Over many decades you are pretty sure to come out ahead and sometimes you get an up year first so it gets exciting.
I have lost as much as 13K in a single day but just wish I could buy more when it is on sale.

Answer 2

A piggy bank.
