Competition is something that we’re made to do all the way from childhood. Your parents made you compete with other kids in academics, sports, and other things. If you won, you were praised. If you lost, you were consoled.
As an adult, you competed in university, and later on in the workplace. Everyone wants to be better than everyone else.
It doesn’t have to be that way. You should compete, but instead of competing with others, compete with yourself. Always comparing yourself with others doesn’t end very well.
What’s important is being a better person than you were yesterday. Be a more productive worker. Learn one more thing than you did yesterday. Set a new personal record on your back squat today. Drink one less soda than you did yesterday. As long as you’re better each and every day, you will succeed.
If you don’t compete at all, you stagnate. If you compete with others, you will feel inadequate. Competing with yourself is the best thing you can possibly do.
