After you’ve spent a little time honing your analytical skills, put them to the test by taking on new responsibilities. Taking on new responsibilities in your academic, personal, or professional life will enable you to practice and to further hone the skills you’ve been working on.  Apply for a promotion or a better job. Moving into a more challenging position at work will enable you to further work on and show off your sharpened analytical skills. Take on some volunteer positions. Certain volunteer positions like being a scout leader, little league coach, or a tutor for at risk kids will allow you to use your analytical skills and help others. Improving your analytical skills will do little good if you don’t work to challenge yourself on a daily basis. As a result, make a conscious effort to challenge yourself and to use your analytical skills on small things every day. Using your skills everyday will keep them sharp and make sure you are performing at your best in your private or professional life.  Try to solve complex problems without aid. Instead of using a calculator to compute a math problem, do it in your head or on paper. Avoid the easiest solution or path. While it might seem like a no-brainer to always do the quickest, simplest, or easiest thing to solve a problem, do not. Instead, test yourself by picking the harder way to solve something. Now that you’re confident in your analytical skills, move on and help others improve their skills, too. Not only will you be able to help others hone their skills, but you’ll continue to work on you own skills.  Mentor others at work. Consider starting a blog where you can share your experience with others. Work with your children, friends, or family, who might be struggling with education or professional issues.

TL;DR in Indonesian:
Cari tanggung jawab baru. Tantang diri Anda dengan hal-hal kecil. Ajak orang lain untuk berpikir analitis.
