Compound interest
Everything in life compounds - your thoughts, your habits and your money.
Your thoughts lead to actions, repeated actions become habits, your habits over a long period of time determine your future personal and financial well being.
Feed your mind regularly, books are a great source. Everything there was, there is and there will be has already been thought of or done by another human on this planet and most likely it has also been documented in the form of books. If you can’t read, then just listen. Just a willingness to learn will take you ahead of most people.
When the mind is aware, the right thought patterns can emerge leading to right habits and so forth.
Your money also compounds - both against and for you.
When you take on debt on liabilities, compound interest actively works against you and makes you poorer and miserable as you age.
When you invest or take on debt wisely for assets/business, compound interest works for you and makes you wealthier and happier.
