Summarize the following:
Your first step is to determine what it is you want to achieve. This can be a big change or small one, but taking some time to think about what you hope to achieve is an important first step to success. For example, is your goal to be a happier person? To learn to play an instrument? To get good at a sport? To be healthier? All of these are valid goals. It's up to you to decide what you want. Once you have a general sense of what you want, you need to start thinking about what these goals mean to you. One person's definition of a goal can be very different from another's.  For example, if your goal is to be happier, you need to think about what happiness means to you. What does a happy life look like? What types of things will make you happy? This applies to less overreaching goals as well. If your goal is to learn to play guitar, what does that mean exactly to you? Will you be satisfied with knowing a few chords so people can sing along with you at parties? Or are you striving to be a classical concert guitarist? These are very different definitions of knowing how to play the guitar. It's important to take a little time to think about why you are setting the goals you've chosen. If you think about your motivations, you may find that you end up wanting to revise your goals. For example, imagine your goal is to learn to play the guitar. You stop and think about why, and you realize that it's because you think people who play the guitar are popular at school. This doesn't really suggest dedication to the guitar. It might be a good reason to stop and ask yourself if there's another, easier way to get what you really want, which is more social than musical. Last but not least, you need to decide if your goal is realistic. Sad as it may seem, not every dream can come true. If your goal seems beyond the realm of possibility, it might be time to make a different goal. Imagine you decide it is your dream to be the worlds greatest basketball player. That's a challenging goal for anyone to achieve, but it might be possible for some people. But, if you're only 5 feet (1.5 m) tall, this goal is probably beyond your reach. This sets you up for failure and discouragement. You can still have fun playing basketball with your friends. But, if you're looking to be the best at a sport, you should probably focus on one where height isn't so important.
Decide what you want. Define your terms. Ask why. Determine if it's possible.
