Never let anyone tell you, you are not good enough. If you think you aren't, it usually stems from other people's thoughts about themselves and you picked it up in childhood. You are good enough and you need to remind yourself daily until you believe it.

So for today use an affirmation "I am good enough". Say it throughout the day, throughout the week and month. Set reminders on your phone to say this to yourself 10 times over the course of the day. Place notes where you will see them telling yourself you are good enough. Do whatever it takes to start believing in you.
