Something we can all look forward to having throughout life are mistakes. We all make them, even if we don't admit to them when we do make them. We can always fix them though and some people don't see that, or when they do, they don't do anything to fix it. I admit that I realize my mistakes but I still haven't done anything to make them better. I still mess up. And all of us will mess up more than once. I believe though that there comes a time when we need to figure out what we're doing and figure out how to make things better for our selves. No one can take better care of you than you. That's what it comes down to is everything is up to us. We make a life for ourselves, we fix and make our own mistakes, we depend on ourselves.
Without mistakes in our lives, we would be lost. That is my honest opinion. Making mistakes teaches us things that no one else can teach us. We can be told or warned, but it's not the same effect as learning on your own through your own troubles. Sure, making mistakes always has a person feeling amiss, but we learn to cope, because in the end we are benefiting ourselves.
If you make a mistake and you know you did, think about it. Think about how to fix it and what it is teaching you in the long run. When you know what you did wrong and can help yourself fix it, it's just another step in the direction of responsibility and in my opinion, bettering yourself.
