Start by turning your head slightly during a conversation, this non-verbal cue forces the person you're talking to to give you their full attention and won't understand why.

Write down your thoughts whenever you feel anxious, stressed and frustrated. Believe it or not, you'll be able to focus on your work because you feel like you've shared your thoughts with someone.

Next time, when you start doubting whether you have locked the door, you will remember this strange sentence and it will calm you down.

Want to wake up to the first ring of the alarm?
When your alarm clock goes off, sit up and clench your fists and scream like you're a soccer player who just scored a goal, I know it sounds weird but it helps you get out of bed feeling fresh.

Want to improve your life?
Start laughing - because when you laugh your body's endorphins (a feel-good chemical hormone) brighten your mood, boost your confidence, make you more optimistic and improve your relationship with yourself.

Want to make decisions without being overwhelmed?
Some people think that it is better to have many options. But in reality, having too many options makes you overwhelmed. So, to be an effective decision maker, give yourself fewer options at a time.

Want to boost your confidence?
Stand up straight which can help boost your confidence. Because you are more likely to be more confident when you put yourself in the right posture. It can drastically improve your dating life and help you move up in the workplace.

Want to make yourself appear credible to others?
Warm your hands before shaking hands with others because warm hands give others a friendly impression. Cold hands convey a message of distrust.

Want everyone to say yes to you?
Your request should never be "Can you?" Don't start with the word, it might make the other person subconsciously think it's a theoretical question. If you want yes as an answer then "Can you help me?" Start by saying "I need your help" by avoiding questions like this.
