THE POWER OF HABIT INVESTMENTS:

Let’s take a few examples:

Spend just a few minutes a day studying Anki flashcards, and at the end of a year, you have a ton of new phrases and sentences learned of a new language. Sure, it’s not the same as being fluent, but it’s much better than you were a year ago.
Spend just a few minutes a day doing pushups (even if you can’t do any at first), and by the end of a year, you’ll be much stronger. I’ve seen the same thing happen to me when it comes to lifting weights — I was very weak when I started, and though I’m not going to impress any weightlifters with what I can do now, I’ve made remarkable progress over time.
I started out not being able to run 10 minutes, but started with 7 minutes. Soon I could run 10, then 12, then 15. At the end of my first year of running, I ran a marathon.

Adding little amounts over time makes a huge difference.

It does.
