Background story: My friend likes to boast about his work achievements a lot.
I want to complain about it to others. Which one below is grammatically correct?
The hard concept for me: I don't know if I should use past tense in this case. Since it is about his regular boasting behavior, it seems correct to use present or present perfect. However, I think past tense can work here too...
01 My friend always boasts about what he achieves at work.
02 My friend always boasts about what he achieved at work.
03 My friend always boasts about what he has achieved at work.
04 My friend always likes to boast about the achievements that he accomplishes at work.
05 My friend always likes to boast about the achievements that he accomplished at work.
06 My friend always likes to boast about the achievements that he has accomplished at work.
