How do I learn decision-making skills?

You make decisions every day. For example, what cereal to eat for breakfast. What clothes to wear for work etc. Think about why and how you make those choices. What are the considerations? Such as, what you prefer, why you prefer those. What other choices are there in each situation? When making some decisions you may have to consider the time, i.e. some decisions require immediate attention. Look for the best choices to make. For example, consider the consequences of each decision, on yourself, on others and on the issue.
