How can you develop yourself if you hate who you are today? You can’t win by fighting against your own being but by accepting who you are, appreciating what you have, starting knowing yourself better and once you make a good deal of peace and understanding of you, if you like it better, you can transform into some new being.
A caterpillar doesn’t become a butterfly by hating being a worm. It enjoys life and who it is simply by living a good and healthy life as a caterpillar and when the time comes, it starts the process of transformation.
If you don’t like who you are today, you don’t deserve to be someone better tomorrow.
