We are all a work in progress... So stop beating yourself up with all the negative thoughts, I'm not good enough, I don't have the experience, I don't know enough people, I'm not creative enough. Learn to accept the things that you are, and make that work. Put one foot in front of the other and keep moving, and know that you are a work in progress, and it's all a process.
When you learn to put on that simple pair of black heels and those slacks that you have had for years and just do, you will see the change in your confidence, and motivation and drive. So get up, have another cup of coffee and stop overthinking things. You are a work in Progress, We all are!
