Everyone struggles - it would be weird if you didn't. Unnatural even. But just because someone sees you struggle doesn't mean that they have to see you quit. Because quitting should never be an option. Unless you're in a hot dog eating contest and you're not a professional food competitor, then yeah, you should probably just give that up before you puke.
Feel free to share this with friends and family on social media or pinterest. Or print it out and keep it handy to remind yourself that no matter who sees you struggle you should always keep going.
