How do you become more confident when there's very little to nothing about you to be confident in?

I would not say that I'm a very confident person but I believe everything boils down to what you think and the environment you are in that make you the person that you want to be. I'm lucky to be able to meet friends who are very encouraging and understanding and give me many opportunities to improve on my self-confidence. Most importantly, gain support from friends who are true to you. Listen and believe in praises and take every criticism as a guide for you to improve on. Whenever there is any opportunity for you to go on stage or do any public presentation, seize it! Overcoming your fear will be the major factor in gaining self confidence. Don;t be afraid of mistakes, as avoiding will not make you any better. In fact trying it out a few times will give your more confidence instead as you will be more used to it. The first step is the hardest so don't be too harsh on yourself. Take a small step at a time and you will be able to see the change in you.

I've been through this and I hope you can be a better person. What is important is not what you have currently, but what will you possess in the future. Only old people look at their past glory, but young people always share their dreams and what they want to be in the future. If you don;t have anything to be proud of, be proud that you are going to be a better person every tomorrow and wish you all the best in becoming a better self everyday!

i used to have very low confidence level too and yes my life was affected. My confidence level soared when I got out of the environment I was in, aka, ppl around me. I got friends and other ppl who were supportive of me and never looked down on me which was the main factor in boosting my confidence. But yes it took some time for me to accept ppl then (like keeping silent in a new env for months in order to observe ppl and see who would be most compatible with my character and stuff)

Friends who put you down aren't friends.

Visualisation can be extremely powerful. I remember reading something about a woman who was loacking in confidence, so she used to think of Marilyn Monroe and image herself stepping inside Marilyn's body and becoming like her for a day! If you think of someone (like Marilyn) who is fun and confident and charismatic, without being arrogant, then it might be a good exercise to try.
