For some, success can come pretty naturally, but for others, it's something they struggle with every single day. Either way, it's important to remember that willpower can play just as big of a role in how much a person prospers as natural ability does. Some of the most successful people to have ever lived were not the smartest or the richest, but the people who had the most perseverance. Luckily, these habits are ones you can strive to practice every day to become the most successful version of yourself.
