We have all learned something about life through experience, and there is so much truth in the statement that experience is the best teacher. A lot of us are so afraid of mistakes when the truth is that making your own mistakes is necessary to gain an understanding of life.
A lot of successful people in this world gained their maturity by falling down over and over, learning from the experience, and getting up stronger and smarter. It has also been said that there is no such thing as a bad experience because there is always something new to learn and that can not be bad. Moreover, when you make your own mistakes, you automatically boost your confidence. This is because to make mistakes, one needs to take actions, and actions only come from place of courage.
Always applaud yourself for trying even if you fail because in the end trying is everything that matters. A lot of people after failure lose hope and give up on trying thinking that it is not meant to be. It is important to remember that each time that you fail, you learn something new. You become rich in experiences and you know multiple ways in which things could go wrong.
This way you have a better command on life compared to the person who has always had smooth experiences. You are always more capable of dealing with negative circumstances and emerging victoriously.
That being said, focus on having as many experiences as possible. A wide array of experiences develops your overall being. In an era of consumerism, a lot of people rely on consuming goods for their happiness. This leads to a materialistic attitude that can never truly satisfy you or you inner self. So, instead of investing in material stuff, invest on experiences.
