Most of my teenage years I used to be super shy with no self confidence at all. I remember having a mindset: “I will not start a conversation myself and only start speaking when someone asks me something or starts talking with me”
I had a terrible fixed mindset and thought I will always be like this.
Looking back at what helped me to crawl out of this hole, there were many things, but what layed the foundation was books on self development.
I still remember so vividly how I went to the library and borrowed my first book which was called “Self-confidence”.
After finishing that one book, I gained a whole new perspective and realized “wow, I can actually learn how to be better at social situations”.
Ever since reading that first book, I have been an avid reader, always trying to improve myself on every aspect of life, whether it is social, mental, financial, physical - you name it. There is just so much wisdom in books that can improve your life.
So my idea for you - if you have a teenage relative, friend, siblings etc. Gift them a book on personal development - my recommendation: D. Carnegie - “How to win friends and influence people”.
Best case scenario is that you may change their life forever, worst case scenario is that they won’t read it :)
