To grow to your potential in terms of personal development do not confine yourself to learning soley from personal experience. If you do you will restrict your development greatly. Learn from and leverage the experiences of others. A good teacher or mentor can make a huge difference in any aspect of your life; personal, academic, business, sport etc. They can advise on new things to try, better ways of doing things, costly mistakes to avoid, where to go for more information.
To grow fast, or to grow in areas outside your own direct personal experience you need to learn from others and their experiences, and that comes from the people you meet, the books you read, the audio you listen to, or films you watch.
There’s an old saying, “You are the company you keep ”. You become as those around you, so it’s important to surround yourself with people that are better than you in the areas in which you want to grow, and who will lift you to a higher level of performance. To be a good athlete you compete with superior competition. To improve at maths you find a maths tutor. To achieve business success you interact with successful business people. To be happy be positive and enjoy the company of other positive people. Remember, you will always grow to the level of those around you. This is not new advice, but it is good advice. A couple of thousand years ago it was written in the bible, (Probverbs 13:20), “He that walketh with wise men shall be wise: but a companion of fools shall be destroyed”.
What you experience yourself may be new to you, but not necessarily so to others. You can learn about things without actually experiencing them first hand at all. You can learn from those who have already lived through that experience. You can get accounts of their experiences through talking with them personally, or at a distance through books and videos.
In summary, your success is partly based on how well you are leveraging the life experiences of others and applying those learnings to your own life.
