I like this quote because it means you have to be assertive and proactive in your needs. Whether you're facing discrimination, barriers, or ignorance, you need to know how to address it and solve it.
Too many times I watch vlogs or read stories about people complaining, hence whining, about hardships, about discrimination they endured, about barriers they faced in their daily lives, and so on and all I want to say is "What are you going to do about it?"
Yes it's a good idea to share your experiences as a way to educate others, but you also need to share how you solved the problem or propose a solution, otherwise it comes off as whining.
Be assertive, positive, and proactive in your life!
