Challenge and excitement will exhilarate you today. Seek out new experiences.
If you're going to learn something new and crucial to your life or career, you need to make sure that the learning is both rigorous and relevant. The knowledge, skills and understandings that you develop must be accurate and worthwhile; and what you learn must be something that can be applied directly to your daily life or work. Without rigour and relevance, the learning won't be as robust or as useful as you need it to be.
If you don't communicate your ideas clearly and succinctly, others will lose interest and dismiss what you have to say. Be ready to offer your opinion.
