2. Worrying
Most people don’t realize this, but worrying is one of the most useless things to do in life. Useless, but at the same time it is one the most powerful emotion to a human being. Why? Worrying can do a lot of harm to yourself. It takes up your strength, drains your energy without you doing anything and instills fear inside you. Useless, because worrying gets you nowhere. It is basically a paralyzing effect. You worry about things, but nothing comes off worrying. Instead, you can look to find a solution for the problem that you are worrying about. Or even pray for it. Those two are far better alternatives.
