"But what if I fail? What if it doesn't work?" But what if you continue to do nothing? You're clearly unsatisfied with your life if the desire to make a change even exists in the first place Does it make more sense to guarantee perpetual dissatisfaction or create the possibility of having even a 1% chance of changing your circumstances? When you think about it like this, doing something, literally anything, is better than continuing to do nothing. So why are you trying so hard to justify doing nothing?
