The greatest difficulty in life isn't effort or struggle, but making the right choices.

Life's greatest difficulty isn't effort, nor is it struggle; it's making the right choices. Frankly, making choices is a very mundane process, even one that can't elicit laughter. Therefore, I believe the top-voted answer's logic is clear, but it's not about your life's choices. For most people, only then can they determine their future and find their life's path.
When do you plan to settle down in this city? What kind of person do you aspire to be? First, ask yourself, what kind of person do you want to become? Then, ask yourself, what kind of person will you be in the future. Love affairs aren't the fundamental issues. We have ideals, goals, and pursuits. In love, you have nothing – no technique, no wisdom, no miracles, your ideals have no prospects, your goals lack passion, your pursuits are not grand, there's no wisdom, no richness, and even the city doesn't align with your ideals. Love is merely ornamental. Without ideals, there's no dream, without goals, there's no joy, without skill, there are no miracles, and without miracles, there's no glory. Only ideals remain.
So, what should we do now? We should strive to become a good person, an excellent person, a great person, a sophisticated person, and ultimately, an extraordinary and invincible person. This is the dream you must cultivate yourself. But dreams can be simple – as long as you take action continuously. You must find your core competitive advantage in life. Our lives are destined to be lonely, and the future is uncertain, because you haven't fully embraced all the love within your heart. Find the career you love, and become the person you aspire to be, and you'll reap the rewards of an unyielding self. Human ability isn't about space; it's about time. What we can do is to strengthen our interactions with the outside world, enhance communication with the world, strengthen communication with ourselves, and deepen our contact with all aspects of our living environment. No one can crush your life, and you shouldn't let everyone crush you. Instead, you must stand strong.
Only when your ability extends to a certain extent can you achieve success.
