Awesome text, after a couple of hard months I decided that I was responsible for my own happiness, only me and nobody else, this made me realize how powerful our mind can be when we just switch things in our way of thinking, little things, like you said, doing stuff out of your comfort zone, it's extremely refreshing to embrace life with a positive attitude and just trying your best everyday to be the best version of yourself.
Everyday I aim to do or learn something new, no matter what, by doing this I feel like I'm seizing this chance to be alive and feel very good about my myself and yes, sometimes you can make mistakes but it's all part of the learning process of life, we fall so we can get up and start again. Your post it's very uplifting and hopefully someone who is a having hard time can feel better by your words. Cheers!
