The greatest equalizer is time. We all have 24 hours in a day.
On average, we spend our day like this:
8 hours sleeping.
8 hours working (job/school/kids etc. etc.)
2 hours eating or preparing to eat.
2 hours watching TV or other type of entertainment
2 hours (sometimes more) on social media
That leaves 2 hours in a day to find a way to become more successful then you were the day before. The difference between those who are successful and those who aren't is how they spend their 24 hours.
