The first step that you need to take is to know that you have self esteem issues in the first place and this can be the hardest thing for you to do. Admitting that you have lost some of your confidence and that you need to do something about it can be a hard fact to swallow but you need to start listening to what people close to you are saying about you and one of the most important things you need to understand is that it is their advice that will be the alert you need. Once you know that you have a self-esteem issue, you then need to proceed on to step two.
The next step that you need to take is to actually go out and have a self assessment test done on your self esteem and it is not that difficult to find a qualified psychologist and therapies that can perform this. All you need is a controlled environment and the simple test needs no expensive and involved equipment at all; in fact, all you need is the psychologist, a test full of questions and an appraisal after that. After you get your score, then you will be able to know how you fair and whether or not you need to get something done.
The next thing that you need to do is to find out exactly what are the factors that are causing you to have low self esteem. If it is the environment that you are exposed to and the people that you are in contact with, it is time to change that or adapt to another one. If it is the job you are holding or other activities that are taking up your time, then you need to identify them. If it is within your mind because of your past, then you need to explore therapeutic and regressive methods needed to reconcile yourself with the pat and dredge yourself out of your self esteem hole.
Another thing that is common in an exercise to get back your self confidence is to build up a small journal or list of the strengths and aptitudes that you have as a person. When you are coming up with this list, it is quite important that you get feedback from other sources all over your social circle, your loved ones and sometimes, people who just only got to know you. This way, you can compare what you know about your own abilities versus what people perceive about you in the first place.
Last but not least, you need to celebrate your achievements and your gifts, and do it as often as you can. You need to turn that list into a feel good list that you can turn to uplift your spirits every time you are feeling down. It is like a shot of espresso or whiskey in the morning, it should get you going and make you elated and remind yourself of how good you can be whenever you have doubts of yourself. With this, you can regain your self esteem in no time at all.
