Depends if u want to learn or just do workThe among worst 3, yes I feel 3 still can but must push n push. You won't feel the stress .
Fierce or impatient is usually smart & action oriented people so cant tolerate people who cant meet that expectation and standard
But u will learn the most from them if u humble enough
#3 u will learn nonthing & after a while u will feel frustrated as everything spoon feed. U are taking up his job directly.. stress will come after that too
