Adversities and challenges always offer vital lessons. Personally, all the obstacles I've had in my life have continued to strengthen me. But you may not realise it when it happens. This is well expressed in the words of Walt Disney: "A kick in the teeth may be the best thing in the world for you."
Although regarded as a successful theme park designer and filmmaker, Disney experienced many adversities. He started sketching as a means to emancipate himself from an abusive parent. His cartooning and acting endeavours failed. He eventually succeeded when he developed the character Micky Mouse.
