You are not defined by your current state. No matter where you are right now, no matter how poorly you are doing at this moment, it is not final. It is not a life sentence. Your past does not determine your future.
You are not, nor can you ever be, a loser. Losing, like failure, is an event. It is something that you do, and because this is true, it is something that you can stop doing. Thankfully, it is not something that you are. You can fail before you learn to succeed. You can lose before you learn to win. You can make poor choices before you make better choices.
If what you are doing is not creating the success that you want or need, then you are simply making poor or unhealthy choices. This does not make you a loser; it makes you a person who is not making good choices. Making poor choices is not a permanent state. It isn’t even a permanent trait, even if you have managed to persist at making poor choices for most of your life.
Right now, you can make different choices. Healthier choices are available to you. Those healthier choices are available to you, and to everyone else who has made poor choices, discovered that those choices made their lives infinitely more difficult, and decided to step onto a different path, one that may not reveal itself very easily, and one that will not be easy.
You can choose to eliminate negative belief systems that no longer serve you or that move you further from who you want to be. At any time, you can choose to make better decisions and take the actions that you have avoided up to this point. You can determine that the trajectory of your life needs to dramatically change, and you can take the first step towards your different future. You will not be the first person to have successfully done so.
Right now, there are a good number of people who write and speak about success who describe people with certain beliefs and behaviors as losers. This is unfair. It is said with a conviction and that intimates a finality, and that makes it false.
