"Mere lucks" can be synonymous with chance, coincidence, fortune, serendipity, fluke, or happenstance. These terms can be used to describe a situation where unexpected success or good fortune occurs without any apparent reason or effort. Luck and chance play a significant role in our lives, and sometimes we cannot explain the outcomes of certain events. However, it is essential to remember that relying solely on luck may not always lead to the desired results. Instead, it is always beneficial to combine luck with hard work and determination to achieve success and reach our goals. So, although "mere lucks" can sometimes help us in achieving our objectives, it should not be the sole driving force.
