Because anything worth getting good at is hard.
When you start writing with the intent to publish it online, it is tough to form a proper paragraph, leave alone writing a complete article.
Your first speech may fall flat and make your audience sleep.
Even after 10, 20, or 100 attempts at something worth doing, you may not be as good as you want to be.
In such times, you may experience despair or lose hope.
Don’t. Just find something to love in what you want to get good at.
That way you won’t find it hard to come back to it.
And, when you find a reason to come back to the hard thing, you win half the battle, because when you come back to something often it becomes a habit. A good habit.
And, with a good habit, you are bound to see results. The kind you wanted to see when you started doing the hard thing in the first place.
