What does it mean to be pointless and feel that maybe everything you have done was not worth your time? We all go through this and we all deal with it in different ways.
The problem is that we hold on to too many things. We want to hold on to youth, money, material items and people. All these things keep us from what makes us happy and we forget to think because our minds are full with things.
We just have too much of everything. It is kind of a fear of letting it go because we do not know what is there.
There is nothing pointless, not really. What each individual does is what they do to survive. Yet, that may seem futile to others. Let them think whatever they want. We have to live our lives and not to live for others.
