Getting a really high rate-of-return (how much your investment grows in value) is awesome. But if you invest small ($) but see big returns (%), you still sort of have a small amount ($).

But when your investment account gets really big ($), even small wins (%) feel huge in dollar amounts ($).

40% gain on $4,000 is only $1,600.
4% gain on $400,000 is $16,000.

You could be 10x better and still earn a fraction of the return of someone with a much larger account.  But on the other side of it, if you can get your account big, you could be a “bad” investor and still have a large paycheck.

When your account is small, focus on making it bigger before you focus on large returns. And when possible, do both.
