Leslie Callum Lim

I believe a life worthwhile living is giving your utmost in everything that life entail.

I’m someone who enjoys the process of learning and self betterment — and because of that I’m quite fascinated or I would say, interested in a multitude of different disciplines. I’m into technology, fitness, nutrition, literature, philosophy, coffee brewing, horology as well as things that would make our lives better! I also enjoy travelling too; because it is truly an eye-opening experience to see how people of different cultures function in their daily aspects of life and learn values that are inculcated within them.
