Life lessons ; Everything happens for a good reason even if you dont see it at the time. Life is too short to waste time hating anyone. Make peace with your past so it won't rob you of your future. You don't have to win every argument(unless your a lawyer). Agree to disagree. If a relationship has to be a secret, you shouldn't be in it. Dont compare yourself to others, you have no idea what their journey is all about, envy is a waste of time and if someone's life seems extraordinary it's usually smoke and mirrors. Burn the candles, wear the shoes, use the fancy bed sheets. Every day is special.
No one is in charge of your future but you. Frame every so called 'disaster' with "will it matter in 5 years time?". Time heals almost everything, give time time . Hurt means your human. It's okay to hurt but you gotta be strong and pick yourself back up again.However bad a situation is, it will change.
Don't take yourself too seriously; no one else does.
Nurture your relationships, respect your frienships, make time, dont be reckless with other people's hearts. Stay away from toxic negative people,they will drag you down.(and I should add pathological liars)
Believe in miracles. Have goals however small.
Probably the biggest contributor to health and happiness is Diet. Focus on your DIET. If I could tell my twentysomething year old self it would be to focus on my diet, cut out bread and junk food and stop the binge eating habits . If you eat crap you will feel like crap.
No matter how you feel get up,dress up and show up... the best has yet to come.
