Life is Either a Daring Adventure or Nothing at All
How often do you set yourself a personal goal and actually finalize it? This is something I can highly recommend.
Start small with trivial things, like going for a 30 min. walk every day for a week. And eventually stretch yourself to an 8 or 9 on the pain-scale of what you are able to go through.
Don't do it for recognition or approval from others. Do it solely for your own sake, for the love of it and because you want to see it manifest.
It will strengthen your confidence, self-respect and self-awareness.
