1.Mind your own business. Yes, please mind your own business. When you start being concerned about things which are not related to you, you lose your grip on your thought process which often results in negativity disturbing the mental peace. Basically, your mind starts wandering here and there. As you know that a non-focused mind is evil's workshop hence the germs of negativity and jealousy gain more strength. So next time an unnecessary thought comes to your mind, think whether this is really something you should be worrying for? If not, shun it right away and focus on something positive, practical and fruitful.
2.Surround yourself in positive people. Ignore negative comments and stay away from negative souls. When someone is negative, he spreads negativity and you get affected. Permanently staying with such people will have long term impact on your character so think about your company.
3.Don't think about others too much. Remember the great quote: small minds discuss people; Average minds discuss events; Higher minds discuss ideas and Great minds act in silence. Don't allow your brain to compare yourself to others as this is an insult to yourself. Don't be Jealous; it's a heart killing disease, get rid of it as soon as possible. When you are jealous you focus on finding faults in others even if they don't have. This poisons your soul and steals the mental peace.
4.You can't keep everyone happy. Don't be over sensitive. Be natural and genuine in what you do. Be positive, constructive and ethical in your deeds and then don't really care too much about others. Be aware, don't apply this formula to too closed relations. Develop trust to establish powerful relationships.
5.Control your mood swings as it is an indication of unstable personality. Do it by not being over sensitive to others. Stop being reactive and implosive. Stay calm.
6.Ignore your thoughts about being unlucky. Bad luck happens to everyone. It's not your fault at all. Time whether good or bad, passes quickly. Develop the power of not looking back into your past. Believe in the power of Now. Believe in your skills. Work hard and have faith in God; you will get what you have been entitled for. Be patient and see what God has planned for you. Patience and consistency in your deeds is the key to success.
7.Simplicity in your character and living style can overcome the stress and improve your happiness index. Don't be socially sensitive and start following every single trend your social circle is following.
