>>460129 personality is not completely genetic because medical conditions can alter personality permanently. Stroke for example. Depression for another. Both of these can be caused by non-genetic causes. Strokes from drug use or medications adverse interactions. Depression can be caused by pollution, poor diet, and medications. Allegra, the allergy pill, was banned from the US Air Force after too many pilots committed suicide after starting on it. You see regular people on forums complain of similar suicidal-levels of depression (that weren't there before) after taking Allegra, not everybody, but a few people react to it.
Depression if untreated for more than 3 years can "set" in the brain and become Dysthymia, or a permanent tendency towards depression for life, whether caused by genes, medicines, brain damage, rape trauma, PTSD, etc. So a forever-glum fellow you know may be depressed, but it may not be from his genes.
Learning new languages seems to add a 2nd personality to people (i.e. they act a little differently when you test them in the other language). Traumatic experience, like war or prison or being a victim of crime, also can cause personality changes.
And these are the personality changes _we_notice_. Other changes may happen for reasons we don't even notice. Nature vs. nuture totally oversimplifies what seems to happen to people if you stop thinking in terms of only 2 opposite explanations from pop-psychology.
