Robert Kubica admits that Williams' struggles in 2019 have overshadowed the achievement of making it back to the Formula 1 grid.
Kubica was promoted from test and reserve driver to Williams' race squad for this season, completing an incredible comeback to racing eight years on from suffering life-altering injuries in a rally crash.
Things have turned sour, however, with Williams late to get their car to pre-season testing and the FW42 yet to get fully up to speed with its rivals.
As such, Kubica has finished last on track in all but one of the nine grands prix so far this year and the Pole says even he has occasionally forgotten how much he has achieved this year, although he says it beats not being involved at all.
"I am not regretting what I decided," Kubica told Motorsport.com.
"Frustration is not a correct word, because in the end it is still better being here than sitting on the sofa and watching Formula 1 on the television.
"Definitely I would be more happy if I was fighting higher up and having less problems.
"But all in all, in these last months, unfortunately this difficult situation puts a lot of shadow on what I achieved and how big achievement it was for me to be back here.
"This is something which I also forget, because Formula 1 is a fast sport and everything happens very fast, so you somehow live day-by-day.
"You forget that in the end I achieved something which I was working on for many years."
