Breathe:
This is the simplest meditation you can try to change your mindset. Breath in for 4 seconds, hold your breath for 7 seconds, then slowly breathe out over 8 seconds. The video above last for 5 minutes, but just do it for as long as you feel. It will help with stress, just feel your shoulders relax. It will help you slow down, gives you a small moment for yourself. Try it just before your coffee in the morning. It can help you sleep, just before you go to sleep play the whole 5 minutes. Focus, you have a busy mind try the exercise and get some clarity.
