How to Find Yourself

Do you often feel lost?Do you think you are living somebody else’s life? If yes, discover ways to find yourself by going through the following article.

小题1:__________

If you are thinking, “how to find yourself when you are lost?”, then the first thing to do is to have a rest from everything—work, personal life and all worldly things. Give time to yourself to think why you seem lost. Is it because of overwork? Is it because you are not leading a life that you want to? Or is it because you are not satisfied with the people or things around you? Try to find answers to these questions to determine the cause behind your restlessness.

小题2:__________

For once, instead of being the way others want you to be, be yourself. Look within and find yourself in you. Think about the things that you would want to do if you didn’t have any family responsibility (责任)or any money problems. Think about the kind of relationship (关系)you would want to be in, the place that you would like to stay in, the kind of lifestyle you would like to lead, if you didn’t have the society or people around you, judging all the time. If you really want to know how to find inner peace, then think, what you would want others to describe you as—an honest person? Or adventurous? Or loving, or realistic? Once you look within, you will know the answer and then try to be exactly that.

小题3:__________

Thinking deeply about the past, the time or situations when you were the happiest, is another way to find yourself .Think what you were doing or with whom you were, when you were the happiest. This will help you to identify things that you want to do in life that make you happy and also certain people whose company you enjoy.

小题4:__________

Knowing yourself and determining what you are to do with your life will not come to you in a day or two. Discovering oneself is an ongoing process and it can take months or sometimes even years to truly find yourself. So, it’s important that you keep a written record of all your feelings and thoughts, which you can go through at a later stage. Pour all your emotions and feelings about life in it and who knows may be one day going through it, you will find yourself.

小题5:__________

Once you have discovered what you want to do with your life, make a move for change and self improvement. Even if it means taking up small things such as dancing or painting, go ahead and do it. If you want a career change, plan and take steps so that it can take place smoothly. If you are stuck in a bad relationship and find yourself unable to mend it, break away. At the beginning, you may find yourself slightly unbalanced, but with time everything will be fine.

It is very important for you to truly find yourself, before it is too late. If you do not find yourself now, you will spend your life with somebody you do not even know, i.e. yourself.
