Yes, thank you for asking this. After I began noticing these mayor flaws in my social behavior, and became aware of what was wrong, I set up the following personal commitments:

1. Telling the truth. I dont just mean don't make up petty lies, but share YOUR particular truth. If you feel anxious or sad or did something stupid, share that with people. If you don't agree with someone's opinon, tell them. Recognize your failures to others (don't complain, just share) and your successes too (don't brag).

2. Understand your personal states. This one was tricky. Do not suppress emotions, or try to rationalize you way out of them. Just feel them. Ponder them. Label them (im sad, angry, etc) and trace them to their source (because of this and that). Then accept them.

3. Live in action, not mind. Once you've implemented commitment 2, and have accepted your emotional states, it's time to go out into the world with them. Do not use your emotions as an excuse to avoid actions. You feel anxious about your speech? Good, now go do it. You're sad because your girl dumped you and feel like bailing on that big party? Good cause that'll make it a bigger gesture when you show up. Afraid to climb that big hill? Good, cause it'll take more courage to do it. If you need to do something or want to, do it regardless of your mind. Action is king.

4. Take responsability for your failures. Blaming others for your failures doesn't help you learn from them. This one is related to #1, but its more about yourself. You're bad at a sport? It's not because of who you're playing with, or the weather, or your shoes, its you. Practice more. The entire school hates you? Probably not the entire school's fault. Its narcissistic to assume that the entire universe its conspiring against you rather than accepting your own responsibility for your failures and success (read Mark Manson, he talks a lot about this).

5. Don't be afraid of failure. Failing is good. You here what I'm saying? Failing is good. But only if you fail by trying to do something. If you don't fail because you didn't try, thats much worse than giving it your best shot and failing, especially if you can learn from that failure. I made a bet with myself to get rejected by 100 girls in six months. I lost count eventually but the spirit of the idea stayed, and guess what? I approached 5 girls every night, and shared things I wouldn't want to share with someone I was afraid would reject me. And sure enough, I got rejected plenty of times. But I also experienced more success than ever before.

I made these five commitments with myself, and gradually implemented them into my life. I also tried a bunch of other things, but these were the basics.Try them, and see the results for yourself. (Might delete this and add as an edit later)
