People who accept personal responsibility see the world differently than those who don't.
People who accept personal responsibility . . .
Are more confident
Are more reliable
Have better relationships
Achieve more success
Resolve problems faster
Experience less stress
Why?
They "look in the mirror" and own their strengths and weaknesses and they know any change starts with them. They play an active role in their journey and results. They don't make excuses, point fingers and look for people to blame when things don't go their way. They feel a sense of control and responsibility over their future.
If you are someone who accepts personal responsibility, keep going because the rewards will continue to validate your behavior and attitude. You will be seen as more trustworthy and reliable.
If you don't accept personal responsibility and you tend to blame others when things don't go your way, hopefully you will have opportunities to figure it out. Life will not get any easier. One, you likely won't achieve the successes you want and that will continue to be frustrating. Two, you will create a narrative and perceptions with others that will make it harder for them to trust and feel like they can count on you. People who can't be counted on don't get great opportunities.
I was 24 years old when I really started understanding this and when I did, my whole world changed. Life became easier and my relationships became stronger. My self-confidence grew and others had greater confidence in me as well.
Personal responsibility is by far one of the most important character traits you can develop.
