Your happiness shouldn't hinge solely on your grades, though good grades can contribute to it.
To attain something, you must actively pursue it. Much like how your grades reflect your efforts and self-improvement.
What are your aspirations, and how do you plan to achieve them?
Excuses have no place when striving for your goals. With dedication, success is attainable, albeit requiring time and effort. Persistence yields rewards, as the universe aligns with your endeavors.
Regardless of your past or circumstances, there's always the choice to pursue what's right. Often, the right choices are the most challenging ones.
