Here's an attempt at transliteration ...

lakshmii (prosperity) chooses (upaiti) an industrious, lion-like person.That destiny should be the provider - this only the cowardly say. "Kill" destiny and perform hard work to the best of your ability. If even after you put in effort (you) don't succeed, then whose fault is it?  (i.e., it is not the doer's fault: the effort is important, and the satisfaction, therein. I find it much more practical than the famous shloka from the Bhagavad Gita, in that this is much more practical, and effective piece of advice.)
This is shloka 20 from the subhAshitAratnabhanDAgara.m, under udyama-prasha.msA. A big thank you to Prof. Urjit A. Yajnik (Physics, IITB) for his help in locating the source of this lovely practical shloka, which I had first come across in our X standard Sanskrit textbook. Prof. Yajnik had first helped his junior colleague in 2001, and when this irresponsible junior colleague had lost his notes, he helped him again, 18 years later.
