Social life is very important to women

I was looking in the mirror today ,and a thought hitted me: a woman without a social life will loose the interest in her appearance, even loose the motivation to clean herself up.  Women don't dress up or put on makeup for herself if there is no one to show it to: then there is no need to spend any time doing that .  Actually they are as lazy as men (I mean some men, nowadays men care more and more about their appearance).
So anyway ,the social life is very important to a woman, it will push them to take care of themselves well and help to build their confidence.  so Women should never give up their social lives no matter how bussy they may be with a baby or housework or something.

social life is very important to women

I [first person subject pronoun always capitalised, no matter where it appears - but here it is at the start of the sentence so it is doubly important] was looking in the mirror today,_and a thought hitted ['hitted' is not a word. 'To hit' is an irregular verb and it doesn't change in this context]me: a woman without social life will loose ['loose' is an adjective. In this context, the correct verb is 'to lose] the interest of  [awkward choice of preposition. You take an interest 'IN' something, not 'OF' it, e.g. I am interested IN art.] in her appearance, [you are consistently placing the space BEFORE the comma. Spaces come after the comma.] even lose the motivity [This is the wrong word. 'Motivity' is the ability to move. The correct word is 'motivation', the will to do something.] motivation to clear herself up. [space and capital letter after a full stop.] Women ['Woman' becomes 'Women' in plural form']  don't dress up or put [I would replace this with 'use', so 'don't dress up or use make up'. Otherwise, the correct form would be 'put makeup on'] makeup on for herself themselves. [Since you are using the plural form, then this should be 'themselves' not 'herself' - for consistency. I used a full stop because you are beginning a new idea. You could also use a semi-colon.] If there is no one to show off to [this is a bit awkward. I think you mean 'show off to'. A better choice would be 'to impress'.]  then there is no need to spend any time doing that. [full stop, capital letter] Acctiouly [Spelling. The correct spelling is 'Actually'.] Actually, they are as lazy as men I [capital letter for first person subject pronoun 'I'] mean some men, nowadays men are more and more caring about their appearance).

So anyway, the social life is very important to a woman [I would use a conjunction here to explain why this is the case] because it will push them to take care of themselves well and help to build their confidence. So women should never give up their social lifes [When 'life' becomes plural, it becomes 'lives'] no matter how bussy [One 's' in 'busy'] busy with baby or housework or something.

Here is a re-written version:

I was looking in the mirror today, and a thought hit me: a woman without social life will lose interest in her appearance, and even lose the motivation to clear herself up. Women don't dress up or put on make-up for themselves; if there is no one to impress, then there is no need to spend any time doing that. Actually, they are as lazy as men (I mean some men, as nowadays men are more and more careful of their appearance.)

So anyway, a social life is very important to a woman, as it will push them to take care of themselves and help build their confidence. Women should never give up their social lives no matter how busy they are with baby or housework or anything else.

You're totally right about people and their appearances though. There's no reason to care if no one sees you!
