It takes quite a bit of work to improve. And the worst part is that you'll never finish the work once you start trying to get better at things. You can work until the day you die and you will always be able to improve. You can be the best in the world at something that you invented, and you will always be able to improve.
Work is hard. It takes effort and time and the reward for all of that is just more work.
But the work can become the joy as well. Learning and growing, challenging yourself to constantly get better at what you do, can bring satisfaction that you couldn't find otherwise. The skills that you develop make the product of your work constantly better.
It's hard to learn how to use PowerPoint. It's hard to stop using notes. It's hard work. But it's worth it.
