The word it” in paragraph 2 refers to

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 41 to 47.
Do you have anxiety? Have you tried everything to get over it, but it just keeps coming back? Luckily, whatever your circumstances, you can take action right now to defeat the many different symptoms of anxiety and stop it from affecting your life.
Do you feel anxious when making decisions or find it hard to get things started? One way to overcome indecision is to “do things badly”. This strategy sounds strange, but the reason it works is that it expedites your decision-making process and brings you straight into action. People often wait for the perfect moment to start a project, but this mentality can lead to procrastination and even prevent us from doing it at all. And that causes stress and anxiety. Instead, just start by “doing it badly” without worrying about the results. This will not only make it much easier to begin, but you’ll also find that you’re completing tasks much more quickly than before.
Imagine that you have a friend who always tries to tell you everything that is wrong with you and your life. You would probably want to get rid of them right away. However, people with anxiety often do this to themselves so frequently that they don’t even realize it. So perhaps it’s time to change and start being more empathetic towards ourselves for the mistakes we make. If you feel like you’ve embarrassed yourself in a situation, don’t criticise yourself – simply realise that you have this tendency to blame yourself, then drop the negative thought and redirect your attention back to whatever you were doing and you will feel better right away.
Regardless of how much we work or the amount of money we make, we can’t be truly happy until we know that someone else needs us. This doesn’t mean that we need people’s praise, but doing something with someone else in mind takes the spotlight off of us and our anxieties and places it onto others and how we can help them. So how can you make yourself important in someone else’s life? It could be as simple as taking care of a child or elderly parent, volunteering, or finishing work that might benefit future generations. Even if these people never realise what you’ve done for them, it doesn’t matter because you will know, and this will make you realise the uniqueness and importance of your life.
