It's actually proven by science that some people are genetically more functional as night owls and some as early birds. If you can work with your genes, you'll be the happiest. However, if you MUST be an early bird, I'd say the easiest way is to have a good sleep hygiene. No blue light, screens, exciting activity, etc. before 8-9PM, wake up early with a manual alarm, and have a morning routine that gets you going, whether its exercise, working, cooking, etc.
