The most important agreements are the ones you make with yourself.
The result of those rules – your actions, feelings, and thoughts – is what you call your personality.
Practicing the following 4 agreements in your life is how your best self becomes even better.
The 1st agreement: Be impeccable with your word
Don’t break your word (be it with others or with yourself) and only find kind words for others and especially yourself.
The 2nd agreement: Don’t take anything personally
We make the selfish assumption that everything is about “us”. Realize that anything people do, feel, think, or say, is because of themselves – not because of you.
The 3rd agreement: Don’t make assumptions
The problem with making assumptions is that we believe they are the truth. Don’t be afraid to ask for clarification. Find your voice and ask questions.
The 4th Agreement: Always do your best
If you try to do your best, and you tell yourself so, there is no room for frustration, self-judgment, guilt, or regret. Instead, you slowly learn to accept yourself. Keep in mind that doing your best doesn’t mean that it’s always perfect or successful. Doing your best also doesn’t mean overdoing it.
Keep those 4 agreements in mind, and you will avoid a lot of heartaches – for yourself, and others,
