Many of us are creatures of habit, and when it is a good habit that can be very helpful by ensuring that we do things which are necessary or beneficial. But when it is a bad habit, or one which we no longer think is good although we may have thought so at one time, then we seem to be a prisoner of our past. Despite all our good intentions to change we find that will power is not enough. Our logical minds know that we should change our behaviour but somehow it is just too difficult, and each time we try to change, but fail, this reinforces in us a feeling that we cannot change.
Both hypnotherapy and NLP provide excellent ways of breaking the cycle of failure and so can help you to make the change that you want to make. This is an important point — you must want to make the change — and it is not sufficient for somebody else (e.g. a parent or spouse) to think that you should make the change. If your heart is not in it the change is unlikely to happen.

Examples of behavioural change:

Smoking cessation
Over eating and weight reduction
Insomnia
Nailbiting
Blushing
Addictions
Alcohol (and see http://www.thesundaytimes.co.uk/sto/news/Features/Focus/article78573.ece)
