Struggles in your life help you to measure milestones of progress. Without struggles, there is no progress in life. How is that?
With every struggle, you get to rise up to a challenge and hopefully overcome it. There's beauty in it. You get to reap the fruits of your struggle. With almost every struggle, there is a blessing - something to look forward to - some hidden treasure or gift, which says yes, you have done a good job and you deserve it. This is that milestone of progress.
Say, you want to earn good grades in school. There are competitors around. But that's not the point. You put in your efforts and struggle through your courses to come out on top. There's beauty in it - yes there is. You have the blessing of a good GPA in school which will always work to open up opportunities for good job purposes through your resumes. It is earned only once but work for you in benign ways a lifetime. In fact, it is a milestone of your life's progress.
Now suppose, you have a good job reputation, but you suddenly need to change areas and work in a different zone because of someone's demise, accident, or simply to be near your old parents. Your good job reputation is a milestone of your life's progress which will help you to progress another milestone if you do need to change areas or zones.
Take for instance, you have a challenging health problem. You want to overcome it and live your best life. With the will of your determination, you can rise up to the challenge and beat it - yes, you obviously can. A positive attitude and positive thoughts all along will help you further to cover the milestone of progress. You beat your health problem and give yourself an optimal life to live the rest of your life. How good is that?
How about earning the gold medal for swimming in the Olympics? You have to rehearse a lot. After practices and practices with your coach and fellow mates, you have to prove you are worthy and finally get selected to participate. All along it's been a struggle of struggles. But finally when the grand day comes, you are able to make it and win the desired medal triumphantly. So, on top of everything, it's a milestone of progress.
One milestone leads to another milestone of progress through struggles and winning battles. You pat yourself on the back along the way but not for long. You go on struggling and making milestones of progress until you are lying on your deathbed happy with the minimum regrets. Yes, you have lived a worthy life. You don't regret. You are smug and happy.
