“Have patience. All things are difficult before they become easy.”
Do you remember the first time you rode a bicycle? How about the first time you gave a presentation or spoke publicly? Both are hard and it likely took a lot of effort and energy to master these skills. But through dedication and repetition those difficult tasks become easier and even routine (well, maybe not for public speaking). To master the skill you have to weather the storms and deal with the inevitable setbacks and bruises. The key is to have a goal that is more important than any temporary pain or frustration. Only then you can achieve your dreams.
