If we want to achieve success, we cannot be afraid of hard tasks, but instead, we need to embrace them. And as a result, the harder tasks you complete and the more it becomes a habit for you to do hard tasks, the easier it will become. Why is that?
Instead of complaining, you get in a habit of solving problems and doing those hard tasks. In the end, you don't get afraid whenever a hard task lies ahead, but instead, you embrace it and go for it, knowing that the reward and the joy of completing a hard task lies ahead.
"Embrace the challenge of hard tasks; in their conquest lies the essence of true achievement."
In fact, I believe there is an even greater thing ahead... as you become used to solving and doing hard tasks, you will not look upon them as hard and tough anymore, since it has become a habit for you to do them frequently.
