Is it possible to beat 25% administrative fee (rake) in live tournament?

Hello guys!
My question is this. Is it possible to beat live tournament in the long run,if administrative fee is 25%?
My problem obviously is low bankroll and I can't really afford to take a shot at higher buy ins were administrative fee(rake) much lower percentage wise.
I have very little sample size of results. I am slightly negative after about 100 tournaments. But my wife played about 200 and she has positive results but most of her wins at higher buy ins were administrative fee 20% and 16.6%.
Also at this point, I not concern about slightly negative results of mine because I keep track all my all-in preflop results and it shows that I was quite unlucky with those. And I am wining online where I play much higher volume then in live tournaments.
However, I really want to know what results good/decent player should expect with administrative fee as high as 25%.
