Yes, setting goals is really important. It gives you something to aim for and helps keep you motivated. When you have a goal, you know what you need to do to achieve it, and it can make you work harder. Also, when you reach your goal, you can see how much you've achieved, which is really satisfying and pushes you to set and reach even more goals.

I don't think setting goals is always a good idea. It can create a lot of stress, especially if the goals are hard to achieve. Not everyone likes having strict targets, and some people feel more pressure which can affect their performance. Also, if you don't reach your goals, it can be really disappointing and make you feel like you've failed.

Whether setting goals is beneficial can depend on the person and the situation. If the goals are realistic and achievable, they can be very helpful. But it's also important to be flexible because sometimes situations change and sticking too rigidly to a goal might not be the best approach. Goals aren't for everyone, and some people might find they do better without them.
