Investing in yourself is like taking a penny, and doubling it every day. If you did that for a month, how much would you end up with? $100? $1,000? $100,000? Nope. Not even close! If you start with just a penny, and double it every day for 31 days, you end up with $21,474,836. Personal growth is like that. Practice one thing with excellence daily, and you will get a significant return.

What can you improve by some small percentage? Can you organize your desk? Rearrange your calendar to get more out of your day? Just a bit better at the most important task you do for work? Read a book to broaden your thinking? Any small change that makes you better is worth making. Because small changes add up to major improvement over time.
Make one tiny change a day.
