Generally, you didn't choose wrong words. But you need to know why you made the mistake that you said "살습니다." If not, you will make same mistake again. 

I understand why you made that mistake exactly because I've been studying English by myself.

살다. / The infinitive of the word 'live'

-습니다 / This ending is proper for past tense. Well, the appropriate ending for present tense is '니다.' But there are some rules to use the ending '-니다' properly.

1. Last consonant ㅂ + 니다.

2. 습+니다. 

In the first example, you need to say '갑니다'(the verb '가다'+'last consonant 'ㅂ+니다) You can't say 가습니다. The most distinctive rule is what last consonant in the verb is. There is no final consonant at the word '가'. In this case, the consonant 'ㅂ' will be the final consonant of the verb.There are more rules, such as 'a verb has last consonant ㄴ or ㄹ or ㅇ will use the way 'ㅂ+니다' and change its final consonant ㄴ,ㄹ,ㅇ to ㅂ.

ex) 날다.(fly) will be changed to 납니다. The final consonant 'ㄹ' of the verb '날' is changed to 'ㅂ'

I will give you a case to explain the second example. 

먹다.(eat) will be changed to 먹습니다. Because the verb 먹 has the final consonant 'ㄱ'

Anyway you wrote well and I could have understood everything you were gonna say. Just make a note, correction without why will not help you.
