We live in a world in which survival is only for the strongest. If you are not strong enough in life, you will fail to survive amongst the strong. Therefore, you must learn, train, and make changes and developments. You must make progress regularly and benefit from your experiences and mistakes and also from the experiences and mistakes of others, as we must benefit from others not only from ourselves.
You are currently writing the story of your own life, minute by minute. So, make it a story worthy to be read.
