Blue light filters on all your devices before sunset. Get in bed an hour before you expect yourself to sleep and do something relaxing like listen to an audio book. Live a life that you can be truly proud of (e.g. be productive, socialize, laugh). Reduce negative things and/or negative people from your life. Always have goals in the short and long term for life but balance it out with fun so you don’t burnout. Goals are important because accomplishments improve self-esteem.
