Start living in the moment
If you want to start living life happily, start optimizing every moment. There is no point in dwelling in the past and there is absolutely no sense in worrying about the future. What is in your control is today, what you want to do can be done at the moment.
Give your 100% focus on one thing. If you are with your family enjoy each moment if you are with your friends make the most of the time. If you are handling a project give it your best.
Believe in yourself
To be able to take up higher risks and bigger challenges, one must be highly confident. Self-confidence originates with belief in your capabilities, talents, and knowledge. Success will only be possible with the help of strong self-belief in you.
Even if you know you will be trying something out with uncertain outcomes, believe in yourself that you can bring out the necessary results.
