Summarize this article:

If you feel like you're in a rut or can't improve a certain skill, changing the way you practice can help you approach your weaknesses through a unique lens. Focus your practicing sessions on your specific weakness, and try a variety of different exercises to strengthen your abilities. If you're learning to write poetry, for example, you could practice annotating poetry for a few sessions instead of freewriting. Meeting other people who are learning a new task could help you find new ways of approaching a topic and strengthening weaknesses. Find a practice group or club at your school or community center, or ask others practicing the same skill if they know of any groups.  You could, for example, join a community basketball team if you're having trouble learning to dunk. If you can't find any groups in your area, you can always make your own instead. Sometimes, changing the way you evaluate your abilities can help you spot weaknesses and improve your strengths. You might focus on your accuracy or strength, for example, instead of speed or dexterity. Instead of measuring your painting abilities by how many pieces you make a day, for example, you could focus on how you're improving your shading techniques. If you're having a hard time improving, keep practicing and learning more about it every day. Focus on what you're doing well and, as you make progress in your weaknesses, celebrate your strengths to improve your motivation.  Even if the skill doesn't come naturally to you, you may be able to develop and strengthen the skill over time. Try not to beat yourself up about mistakes you make. Mistakes can help you learn more about your technique and avoid issues in the future.
Change your practicing habits if you feel stuck. Join a study or practice group. Evaluate your improvement by a new measurement. Don't give up if you struggle with a specific skill.
