I have written the following sentence, but I think that I should use an "AND" between "down" and "Success", on the other side, by doing so, the phrase would become rather ugly and awkward (3 "and" among 4 words), should I use a comma or something like "as well as"? and what about the rest of the sentence. Is it academic for a SOP?
Throughout my personal and professional careers, I have encountered ups and downs, success and challenges, which have made me well experienced in handling problems in critical situations.
