What you create today will benefit others tomorrow.
Take a moment today to do something for yourself. There is a lot happening in your life at this time and you are being pulled in many different directions by a range of forces. You have high expectations of yourself, but you're also demanding too much of yourself as you try to please everyone and work towards your own goals at the same time. Don't drive yourself to exhaustion; if you don't give yourself a break every now and then, you could burn out and lose momentum.
Stop apologising. The word sorry is meant for genuine situations where you have caused harm. Overusing it in the workplace can make you appear timid.
