Kaizen is a Japanese philosophy of continous improvement of working practices, personal efficiency, etc. Basically, the idea is to improve 1% everyday.
When you work on building yourself, you should not compare yourself to others. They are not you and you are not them. They more than likely were raised differently, think differently, and act differently.
Compare yourself to the you from yesterday. As long as you are better than the you from a few moments ago, then you are already improving.
It’s that simple. Just keep improving. Slowly but surely you will reach your destination.
