There is a comment in TS's latest video saying that Tiffany posted on Instagram saying that she is happy and complete. Great! The asterisk here should be that she is complete with Youtube, and incomplete without it on many fronts, namely, financial.
What does 'complete' mean with regard to a human? In the physical sense, that would mean that one has all of one's 'very important organs'. Therefore, Tiffany does not mean 'complete' in the physical sense. She means she is 'complete' in all her wants and needs, perhaps. That may be true, but she is clearly not complete without Youtube. She is unable to rely solely on Matt's income and on her little income from optometry. Therefore, she needs Youtube to complete her finances.
If Tiffany did not need the extra cash, she wouldn't be consistently uploading videos that have very little substance. Perhaps she also needs Youtube as an emotional crutch, as lots of her followers send her compliments. Tiffany may feel complete, but that completeness is thanks to Matt AND Youtube. Tiffany is either unwilling or unable to live without uploading videos to Youtube. Both Youtube and Matt complete Tiffany's life. Tiffany might, of course, say that she doesn't need Youtube, and that she uploads because her audience wants her to. The latter is simply an excuse, because, as she says for other things like holidays: She needs to prove or justify nothing to others. If Tiffany ever says that she doesn't need Youtube, I would say: Then, Tiffany, prove it and upload nothing for at least six months.
We all know here that Youtube gives her all that extra cash, which is the main reason why she will not stop uploading videos.
