How people treat you is how they feel about you.
There are people who will treat you like you walk on water, and there are people who will treat you like you're the dirt they walk on. You have the choice as to whom you let stay in your life.
You can't change people.
There are only so many times you make excuses for people before you have to just realize they may not care. This doesn't make them a bad person, just not a person you need to put your energy into.
Never apologize for your feelings.
You have the right to feel happy, upset, disappointed, anything. Don't let anyone tell you your feelings don't matter, or you're over-reacting.
It's okay to be bored.
I'm a person who wants to be around people and doing something all day, but sometimes it's okay to take a step back and spend time alone. Go to a movie, read a book or take a walk. Remind yourself of your dreams and that you are capable of getting there without all those people around.
God is capable of amazing things.
The power of prayer is incredible and the miracles of God are even moreso. He gives you what He knows you can handle and will bring you up when you least expect it, so always walk by faith.
Work hard and enjoy the ride.
No one wants to go into work everyday, but if you make your time there worthwhile and enjoy the people you're with it makes it much better. Work hard, stay humble and never stop striving to be better.
Appreciate those around you.
You were blessed enough to wake up this morning and spend another day with those you love. You never know when either of you could lose that, so cherish the times with those around you. Tell them you love them. Don’t hold things in and always be thankful.
Don't hold grudges.
Holding that anger is like holding hot coal with the plan to throw it at someone else; you're the only one who gets burned. So forgive, forget and move on. Allowing someone to keep you angry only wastes perfect happiness.
