Quite often we sit in our own little bubble thinking only of ourselves and our own needs. While this is important, in that if we can't take of ourselves, how can we expect to take care of others? - it is important this doesn't become our whole Universe.
Life is but a fleeting moment on this blue ball we inhabit.
Don't forget to spend time with those you love, telling them how much you love them. Don't be so busy in life that you don't actually live life. Take a risk now and again. Do something just for the sake of it.
Don't judge another's life based on your own, you do not have that right. Everyone's path is unique and their own. Own yours and stop making excuses and making apologies just because something may not fit with you right now.
In a single blink, things could change dramatically so live life to the fullest and never judge another by your own story, that is your story. At least be truthful and own it.
