Should I care what people think in life?

like i always wear cheap jeans & shoes & tea shirts at work i work retail or outside of work

people who i used to work with tell me to dress better & style my hair as i just let it grow & then get crew cuts then redo once its time again for a hair cute.

i like how i dress & i dont care of people think.

but i was thinking what my dead father said to me once you should care what people think about you.
