We live in a world of continuous comparison to others, measuring our self-worth by someone else's standards.
In an interesting interview by Oz with Jordan Peterson, Peterson says that it's not a fair race to compare yourself to someone else because you don't know anything about the people to whom you're comparing yourself. You only can scratch the surface, but you really don't know anything about what these people are dealing with, and almost everyone is dealing with some serious problem. You create a relative status and a not helpful illusion.
How can we cultivate acting better today for a more successful tomorrow?
First, you need to start with humility. You have to be humble enough to ask yourself who you are and where your flaws are. What small things could you do to improve it? Second, humility to recognize that you need to start small. Above your level of competence, something that challenges you, but you have a reasonable probability of succeeding so that you can continue with the small improvement process.
The best person to compare yourself to is your yesterday self and not someone else today. You could be better than you are and make incremental improvements. Small improvements compound, and you can start moving ahead with the consistency of small improvements.
