Mistakes I wish I could correct

Life is a long journey which consists of various parts. For each part, we have to determine which ways we choose. If we chose the wrong way, it would be difficult for us to reach our destinations. However, we have to accept that everybody makes a mistake in their life and we can't hope to choose the right one all the time. We need to learn from our mistakes and use these experiences in our lives. But, we still have something we can't move on and want to correct keenly. In my case, it's all about my childhood. I wonder what the difference would be if I chose different parts. Suppose I can time travel to my childhood, I would like to remind myself from the past not to do the same mistakes. One thing's for sure, I won't rely on others again. I know the disadvantages of always counting on the family. I remember how exactly I was incompetent before. I used to be the shy and honest one who always follows the regulations. Now, I realize being good is not enough for our complicated world. We also need to be unique and smart. This world is challenging and a lot of difficulties are waiting for us throughout our lives. I was terrible at solving problems and I preferred running away from problems rather than solving them. That's the reason I made a lot of mistakes. Moreover, I wish I can change my physical condition. As I was an outstanding student, I used most of my time to study which resulted in a lack of physical abilities. To be a strong and confident person, we not only need mental abilities but also physical ones. You will be healthy if you're physically strong and we need to build up those capacities since our childhood. I'm sure that I would have solved a lot of problems if I had had those potentials. In reality, we can neither time travel nor correct our previous mistakes. The best solution is to remind ourselves about our mistakes and stay alert in case we find similar situations. If we're cautious about every action we take, we can achieve our goals shortly.
