I wanna know what kind of lie we should avoid

Like I don’t wanna tell anyone if I’m working or not or what my income is and if I just straight up tell people that I don’t wanna share they will think of me as rude or not good

Or people get jealous so I don’t wanna tell them so I lie when they ask about it

Second is that when applying for work or online work they usually ask how much experience we have and where we are from if we say from Pakistan they pay us less so we pretend to be from Europe or some better country

But work they get is high quality and up to standards

Can you please elaborate on that if that’s ok to do or something to avoid if possible or at all cost ?
