There is no gain in lacking self-confidence as an adult, getting angry all the time does not make you look better either. It is only when you grow into that smart, confident and calm person that you can attract good people into your life.
The goal is to work on yourself first. Develop everything about you, your mindset, attitude, self-esteem, self-confidence, and every other things will fall in place. You have to be aware of yourself first before you can develop, know your weakness and your strength, and manage them.
The problem with most of us is that we do not care to invest our time in working on ourselves, but we expect to get better and attract good people. At the end of it all, you actually attract the person that you become.
People will only choose to be with you, when you yourself have chosen to become the better version of you. It is not just about running fast, but by moving on your own pace in the right lane,you are allowed to take few steps but in the right direction. Your future is at the mercy of what you invest in the present which is now.
We are used to living in the comfort zone that deny us of self confidence, not good enough and a better version of yourself. All this are weakness are something that we should never be proud of especially when we have crossed a certain age of maturity.
Everyone at some certain age should be free from some of the weakness that hinders us from making progress in life.
