We create our own surroundings by the thoughts we think. Thoughts are deeds. If we learn to use what we have, we will receive more. This is a spiritual law. We will be given all that we are prepared to receive.
Mistakes are an acceptable part of being human.
We are to make all the mistakes we want. Mistakes are how we learn. The key is to try and not make the same mistakes again. God loves us the way we are - mistakes and all. When we make mistakes we should seek forgiveness, learn from the mistake, let go of guilt, and try not to repeat it.
