If you are serious about gaining self-confidence then you will need to find out what is working in your life and what is not working for you, because you will need to fix what is lacking in your life before you can proceed.
Within the law of attraction you will find ways to gain the self confidence that you lack, you may also find things about yourself that you do not like, but by finding these things out you can get to a point where you can accept not only your perfections but also your many flaws.
You will find within these laws a lot to gain but also a lot to give in order to develop the self-confidence that you seem to lack.
By using the law of attraction, it will advise you to look within yourself and the energy contained in yourself, because the law of attraction is about harnessing your positive attitude and finding away to block out the negative energy and thoughts that can develop if you start to let things get to you.
The key is to find a way to relax, and then being able to block out those negative feelings and focus on the positive feelings as they surface.
There are many ways do this, Yoga classes, Pilates; etc even take up a sport, the trick is to find something that works for you to aid in reinforcing the positive energy within yourself.
When you use the law of attraction you will be able to focus on the things that matter to you, and not allow others to control your life and to be your own guide.
Gaining self confidence through the law of attraction will give you the power to run your own life, to do the things you really want to do, and by maintaining your positive thoughts and not letting negative influences eat away at your new found confidence you will find this an empowering feeling.
But keep in mind this is not to be taken lightly, using the law of attraction is a serious endeavour for it to work properly.
