It's nice you try and find ways of dealing with your life from the old philosophers. I must admit, though I know a little of all the different thoughts the Greeks had back in the days, I never really dug into it. I tend to go through life using my own logic. Acceptance is super important I think, ie accepting a situation or something. For sure, when the situations are out of your control. But even, sometimes also when they are in your control. But just accepting everything is not the way to go, I believe. The best is to have backup plans for any goal one sets. Essentially the question one shall try to answer: "What makes me happy, and what if I can't reach this or that goal? What is the minimum I need to be and/or stay happy?" The answer to those questions becomes the baseline in life. I personally think this baseline is all about who you like to be, what peeps you like to have around you and enjoying the moments whatever moments they are. Anything else becomes irrelevant. Not saying that no other goals can or shall be set (eg certain income, certain job, certain place of living), but when the goal is not achieved or reachable, acceptance becomes easier.
