My therapist dropped a gem: you can't spend your life avoiding heartbreak or bad things from happening. You have to condition yourself to have appropriate emotional responses but learn to keep moving forward.
i think it's important to have something to look forward to every day or every week, so when life drains you, it’ll help you to remember that you need to keep going a little longer because there's something waiting for you at the end of the week that might make you smile again.
