Your need to learn how to behave with people and thing,make your bed each morning, clean your room/house, never have to think if today you can or not have someone in your place.
Find people to paddle with you, learn how they behave before becoming their fren, measure the size of heart and the though of their spirit. Learn to discern people showing of or being true.
You will get hit, you will failed, you will be beaten. When it will come to you, be the better of yourself in this kind of situation. You will hit some one, you will success, you will be victorious.Life is struggle, win and loss. In any case keep moving forward.
What you do is what you are to other people eyes, they are not on your minds and even if you said so if you do the opposite your words mean nothing. Think before saying something, and double thing before yo do. The two need to match but never be afraid of saying and doing.
Don't always think about it, sometimes you have to slide down obstacles head first, professionnaly, amically and even most with love. It's all in or it's nothing.
And finally be a example, not nesserly a leader, but a exemple. Someone relatable. Keep yours words, bring back to your friends, community or whatever. Even more if your introvert, make your action count. Never quit something. Even if it's not perfect, stick to it until it's done. Don't ever stop to learn something, never stop being a better you today that you were yesterday.
If you do this, the world we start to care, and you will care too.
