They aren't important. There are a lot of things that I'm horrible at, but I'm not trying to improve most of those areas.
Instead, I'm focusing on what I'm really good at and trying to make those areas of my life even better.
Many of us get bogged down trying to make up for deficiencies in our lives, when the area of focus can be better spent elsewhere. It's great to improve all areas of our lives, but it is simply impossible to be great, or even good, at everything.
Find what you do well and make that your focus. Where does your passion lie? That's the path you should follow. If you don't like accounting, outsource it. If speaking isn't your thing, write articles.
Don't focus on the negatives in life. Instead focus on the positives and make them even better!
