As an adult, you should know right from wrong? To make a determination not to drink alcohol is usually considered a wise choice for many reasons (none of which you mentioned but you know why). Then later on, change one’s mind and start drinking alcohol. An error? A mistake? Yes, it was a mistake. It was a poor choice.

Do you beat yourself up about it? That depends upon the consequences of the bad choice. Drive drunk? Get into a fight? Forgot someone or something that needed to be done? Wasn’t where you were suppose to be? Addiction? Asking yourself what constitutes a mistake is just looking for excuses for your actions.

It seems it is time for one to be responsible for one’s actions. Not to look for excuses. Not to look to blame others. Your choices now will build the foundation of your future. Wish you well.
