Hinduism calls it Karma yoga[1] - the path of selfless action. It is portrayed in no way inferior to other approaches. Do you work well with passion without attachment towards results.
I assume by "results" you mean recompense or renown, since you mention doing work "well". I only mention it because to me "results" are what I use to define whether my work was done well, and aren't what I think of when considering whether it was materially beneficial for me.
Getting those rewards might represent their own bit of karma yoga, with separate effort.
It is silly to think a divine entity is going to descend from the heavens to ensure that you get your just rewards for doing a good job.
