There is one thing i know about Affirmation, "Affirmation can change you perspertive". I mean the way you view things, to a positive way. This can help you to create a positive mindset.

Morning Affirmation: This can be better used early in the morning before going out from your room. You can try something like;
"Everyday is full of potential and i am open to new opportunities".
"I am grateful for everything today".
"I am capable of creating the life i dream of".
"I tackle challenging task that comes my way with ease".
"Today, i choose to celebrate all the progress i have made to get here".
"I exactly where i am meant to be, and heading in the right direction".
"I am worthy of my own love and respect".
"I have many positive qualities including; money magnet, people magnet, positive customers, positive and potential partner".
I choose to accept myself the way i am today".
"Everyday i am getting closer to reaching my goals"...
Always try this each time you wakes up, it's going to help you. Thanks.
