Let me explain...
Reality is that the glass is always full, unless you live on the cusp of a black hole and half your glass is in it. It is full of air, water, juice, or whatever cool-aid your drinking today including this philosophical bullshit. It is still full though, and anyone telling you it is not is trying to sell you something for your glass.In life...
You have not had time for anything more than you already did. You don't get a chance to do it twice. Your cup is always full. You put more cool aid in and you lose air. You know what happens when your brain loses air? You don't die right away, instead you turn into a clumsy, stumbling, walking blueberry.So...
The cup is overfilling. It always is. Air is spilling in and out, and if that cup is sideways you might only have air in your cup. Make your cup straight and put what you want in it.I'm sorry, your hard life has only given you half the blessings you deserve.
For heavens sake.. Stop believing there is a void in your cup!
