It is never too late to make a change and taking some much needed alone time for yourself to reflect is not selfish.
Always take time to cherish every single moment you get, and always take a second to remind yourself how special that moment truly is and just how lucky you are to have it... remember that there is someone somewhere wishing it was their moment.
Every second that passes is another grain of sand in your hourglass that is gone, forever lost in time.
