Time is life. If I know how you spend your time, I can predict your future. Have you ever seen any poor person who values time? Have you ever seen a successful person who does not value time?
Always carry something to read. In a queue, while all people are complaining; as a success minded person, make sure you are reading. While travelling, carry a book to read. Your mind is the most crucial part of you. Develop it and you never regret. Self education is the most fruitful type of education.
School education can not make you happier, healthier or wealthier; so educate self. Every month use 5 to 10% of your earnings to buy books, attend seminars etc. Some people spend too much on the body than the mind. Reflect on this.
