I've done a few "hard" things in my life: getting my PhD was hard, being a parent had some hard times, just living life can be hard. However, building the SPARCs for Good platform has been very hard. Yet, super fulfilling. One lesson... hmm. I would say the wisdom of Austin Kleon keeps coming back to me from his book "Keep Going." "If you love what you're creating, so will someone else. Go find them."

Not everyone will like what you are doing. And those people very well might be the people closest to you, the people you really "want" to love what you are doing. However, the world is a very big place. If what you're doing really has value, there are people just waiting to see what you have created. But you have to go out and find them. Keep going until you do.
