this is a tough question because its all relative.

Your personal time is worth a lot. People don’t realize this. Your personal time is how you live and grow as a person. Its when you’re supposed to be fostering your relationships: watch your kids grow, pet your dog or cat, get to know your relatives, chill out with friends, participate in some group classes/hobbies.

So.. whenever you are asked by another human being to give up that time to and spend it on advancing someone elses projects (whether thats a job, collaboration, or relationships) .. you really need to contemplate what youre giving up to help them. Money is a bribe.
