Human beings will tell themselves what is possible relates to what is common, typical or normal in the world around them. As you evolve to compare and judge yourself, you reject, criticize and evoke repeated discomfort. All your senses reveal useful things.
For example, if your dream is to be a model, to work in media, or in some other public role, yet, your self-image tells you that you do not have what it takes, you may lose faith in your ability. You can also read your senses as encouraging new initiatives for self-growth. What matters is you devote yourself to what you do. Learn wherever you are.
If you do not feel you have much in common with anyone you know or have met, you may wonder whether you are coming or going, if you have a place in this world at all. Uncertainty and confusion may evoke more of the same. All emotions, even anger, are raising your awareness of something. You can view this as helpful. Take it as you will.
The short answer is, of course you are meant to exist right now. If you were not supposed to be here, you would not be alive now. It is often easier to figure out what you are not, what does not feel right, what does not "jive" with your inner self or the people around you. All of this offers clues and points you in meaningful directions.
It can be tempting to search for a single recipe or answer to explain who you are or what you are here. This is conditioned thinking. When people around you are making certain choices, only you are equipped to decide what is right for you. Different is beautiful.
Each opportunity to make a new decision is a way to learn about yourself. Happiness is experienced throughout your life. How you feel at a given moment is always a choice. This empowers you to dream and define what is 'normal' for you. What about right now?
