Life is an experiment
Whatever that has happened in your past, whatever standards and self-image you believe you need to live by, there is no commitment you need to force upon yourself.
As you continue to learn and evolve, your understanding in life changes and your new insights will offer you new results.
Allow yourself the mistakes of your past and don't hold onto it like you have should known because you didn't.
Go into the future knowing there is more you still do not fully know and will continue to make refine and make mistakes as life takes you into new experiences.
Enjoy life as an experience, not as a way to define you.
