You are responsible for the state of your life right now. You have the ability to make changes and own up to the decisions you have made by embracing them and extracting the value and experience you have gained from them. By realizing you are in control of your life, you can be more effective in identifying the things you wish to improve or change about yourself.
Rather than bragging to others about all of your accomplishments, instead ask people about theirs. Respectful listening to the successes of others can help you to gain insight into your own inner life as well as allowing you to connect with others in a meaningful way.
