The following tips are based on my own experiences.
1) Start Investing at a young age as investment will get time to grow in compound manner.
2) Dont invest all your money in One Stock or share.
3) Do not depend on Stock experts to suggest you where to invest money .
4) Keep a Record of your stock performances
& Learn by your mistakes .
5) Develop Quick decision making skills.
6) Do not get Emotionally Attached with any Stock.
7) You are Responsible for your PROFIT as well as for your LOSSES, and not the MARKET.
8) Market is not Gambling, its an Art, master it.
9) Develop positive attitude towards life .
Its not winter all the year . Summer too is necessary.
10) Focus on Learning, more than that of Earning.
All the best
