Since teapot riddles are getting popular, I thought that I should give it a go
Rules: I have one word which has several (2 or more) meanings
Each of the meanings is a teapot (first, second ...)
You try to figure out the word with my hints.
Hint 1 :
My first teapot is possessive
My second is what you have to work on
While the third is dangerous
Hint 2 :
My first teapot can be self-centered
My second can actually make you rich
The third you have to watch your step literally
Will add more hints in the future
