What you think, you become. Thinking is very important to us as ideas can be generated by thinking. The mind is never idle, it is continuously bombarded with innumerable thoughts which may be related to each other or bizarre. Till the time you are awake, your thought process continues. It is very difficult to keep the mind blank; so instead of clouding it with useless thoughts, think positive and logical. People with positive thoughts have longevity. Also you can achieve your goals faster with a positive mindset, as negativity hinders your progress.

Positive thinking is a state of mind in which you see the bright side of life. If you think positive only good thought will dominate your mind and you will flourish in happiness, success and health. You will always look at the goals and overcome the hurdles without any difficulty. It is indeed a remarkable asset if you are a positive thinker. Then you have a power to change things around you. Happy people don't get into jealousy; rather they work hard all the time to achieve success. A positive attitude makes you happier as your brain discharges endorphins which gives you the feel well-being. You also have optimism in you and your interpretation of the people around you will be good. You have to keep your goals clear and as you are positive you will accomplish the same. Even in failure positive thinking will enable to think. That's good as for you as if one door closes another opens up. If you search goodness in anyone you will surely find it. As Winston Churchill had said, 'The pessimist sees difficulty in every opportunity. The optimist sees the opportunity in every difficulty'.
Positive thinkers learn the hard lessons from every setback. Instead of getting perplexed and blaming others for what has happened, they remain firm and seek answer to the question, 'What can be learnt from this setback?' Rather than going into isolation, they spread positive thoughts which reflect their attitude to people around them.
Live in the present: Forget about the old problems and bad memories. Stay with happy people rather than glum people. Happiness is contagious and that is why happy people give blessing rather than curses and blames. Think that the other person has good intentions.
Don't look for perfection: Perfection is very difficult and aspiring for it puts you under great pressure. Life is actually not completely in your control, so don't waste your energy and time in negative thoughts.
Talk in positive language: Stop negations completely. Analyse how much you are saying negative things. Attempt to reclineto positive thinking when you wake up and see how beautiful the world is.
Keep learning continuously: The learning curve should never stop. Learning new things is quite energetic and your perspective to look at the things change.
Be thankful: You can have gratitude towards all those people who have affected your life. Thank all people around you who have made this world a wonderful place to live.
