We all know that we have to die someday but life ain't about being negative, its about moving forward and being positive. Everything will come to an end but that doesn't stop us from living. Get up and enjoy every moment of your life while you can. Remember- You Only Live Once, so why be negative about it.
The answer to your questions has rather philosophical tones. It's true that we will die one day. It is also true that we were born, and with the environment that was offered to us, we grew into who we are today.
Until the time of our death, we live.
For as long as we live, we strive for a purpose, whatever that may be. For some it is to have thriving relationships, for others it is contributing to society, and for some it is success, wealth or power, or all.
Even at this time when there is so much fear and uncertainty, it may serve to consider what is it that we value and how we may want it to grow.
I know that this is a difficult task. But please know you are anot alone. Many people are struggling with the same feelings.
Please don't give up. Remind yourself of what you value. This is the time to redefine how you will create it.
Invest your energies in this endeavour.
Don't give up and don't loose hope.
