You’re not always going to see the results of your work. You’re going to get results, but it might not look like what you thought it might.
Trust that your work is meaningful. If you are sincere and do the work then it is having an impact. If you need clear evidence of your efforts every single time you do something then you’ll burn out quickly.
Is your work something you can do without constant positive reinforcement?
The work benefits you, the results benefit the people you serve.
