Can I Break My Habit?

You can break your habit if you are willing to consider a new perspective:

Remember you were not born with your bad habit, you learnt it and you can unlearn it.
You've practised doing your habit to the extent that you are good and skilled at it. Now is the time to stop and become good at doing something else.
Don't look for scapegoats and blame others, be willing and responsible for breaking your unwanted habit.
Don't label your habits good or bad, they are just things you do. The question is "do you wish to carry on doing them ?"
If you believe that you can and you believe that you can't, you're right. Remember you get what you focus. If you focus on how hard and difficult it is to break a habit then that's exactly how it will be.
The best way to stop a habit is to first imagine yourself having conquered it. Take the time to act out in your mind you being in total control.
Repetition is the mother of all skill so when you've acted it out in your mind many times, just like how a great actor would, then take the time to act it out for real.
Remember success is often on the other side of failure so you don't have to get everything right straight away. If you make a mistake and back slide then learn from it and move on.
Be patient and give yourself the opportunity and the time to change.
